Interface and connectivity ICs

Posted on October 19, 2015 at 16:54Hai Guys !I am using SPWF01SC.11 , I have connected this with the micro controller via UART.From the micro controller I am sending a command AT+S.SOCKD= port number through UART.Now my WiFi module received the command and entered into the data mode.I know the IP address and port number of the wifi module now and  i connected it from my computer.Now I have a sent the  string ' Hai' from my computer and I can see the string in the data mode on hyper terminal.My question :  1. what will happen on the wifi module once it received the string in the data mode ?2. will it send the string through UART ? #spwf01s-wifi #spwf01sa-wifi-scan-command

Posted on October 19, 2015 at 08:58Suppose I set an advertiser in scan mode - SCAN_RSP. Is the Client (Central role) can send the scan request with its own user data?

Posted on October 11, 2015 at 15:14Hi everybody, I have troubles to connect the SPWF01 with an AP using WPA2 privacy mode. When I try to connect, after Wind 25: association successful, I receive Wind 40: deauthentication:1 +WIND:19:WiFi Join:00:04:ED:61:FB:18 +WIND:25:WiFi Association with 'Alison' successful +WIND:40:WiFi Deauthentication:1 +WIND:74:Rejected found Network I have another AP and I can link with it using the same security mode and the same password, hence my code should be right. +WIND:19:WiFi Join:14:CC:20:9C:D5:4D +WIND:25:WiFi Association with 'Alison_EXT' successful +WIND:51:WPA Handshake Complete +WIND:24:WiFi Up:192.168.1.110 I did a scan and the APs are in WPA2 for sure: 1: BSS 00:04:ED:61:FB:18 CHAN: 06 RSSI: -59 SSID: 'Alison' CAPS: 0411 WPA2 2: BSS 14:CC:20:9C:D5:4D CHAN: 06 RSSI: -79 SSID: 'Alison_EXT' CAPS: 0431 WPA WPA2 WPS I think it could be a security issue because I can connect to the bad AP in Open mode. I searched the web for deauthentication:1. It i

Posted on October 09, 2015 at 12:31Hello, we have to transfer long attributes (images) on BlueTooth. We read in BLE Specifications 4.0 that this can be accomplished using the “Write Long Characteristic Values�? procedure described in 4.9.4 of part F: a sequence of Attribute Protocol Prepare Write Request – Prepare Write Response terminated by:Execute Write Request - Execute Write ResponseHowever, looking at the code, it seems that only BlueNRG MS (and not BlueNRG) provides the offset: #define EVT_BLUE_GATT_ATTRIBUTE_MODIFIED          (0x0C01) typedef __packed struct _evt_gatt_attr_modified{   uint16_t conn_handle; /**< The connection handle which modified the attribute. */   uint16_t attr_handle; /**< Handle of the attribute that was modified. */   uint8_t  data_length; /**< The length of the data */ #if BLUENRG_MS ///@cond BLUENRG_MS   uint16_t offset;     /**< Offset from which th

Posted on October 01, 2015 at 09:51Hi, I am broadcasting a small UDP packet once a second through the SPWF01 using AT+S.SOCKON=192.168.1.255,55555,u and AT+S.SOCKW and that appears to work just fine but if I access the SPWF01 web server at the same time to reload some web pages it often dies with a hard fault like this +WIND:8:Hard Fault:TCPIP: r0 2C303035, r1 00000300, r2 00000000, r3 0000FFFF, r12 2000867C, lr 08022E25, pc 08022E3A, psr 61000000 Or the module may just crash, reboot, etc. If I don't do the UDP broadcast, then the module appears reliable. This is very bad as I need to be able to do the UDP broadcast so clients can find the device. Cheers, Mark

Posted on October 05, 2015 at 11:21 My device is configured as a SERVER in an advertising mode. ret = aci_gap_set_discoverable(ADV_NONCONN_IND, 160, 160, PUBLIC_ADDR, NO_WHITE_LIST_USE, sizeof(local_name), local_name, 0, NULL, 0, 0); It sends an advertising beacon with a user data. if (bluenrg_tx_count > period) { bluenrg_tx_count = 0; ret = aci_gap_update_adv_data(sizeof(manuf_data), manuf_data); } The other side - CLIENT reads the data. What if I want to get some data on the SERVER side? Can I do it in the same pattern by getting the advertising data from the CLIEN or should I implement services and characteristics in it?

Posted on October 01, 2015 at 14:45 First I configure the module. void BLUENRG_Setup(void) { HCI_Init(); BlueNRG_RST(); Osal_MemCpy(bdaddr, SERVER_BDADDR, sizeof(SERVER_BDADDR)); /* Configure BlueNRG address as public (its public address is used) - MAC address of the device */ ret = aci_hal_write_config_data(CONFIG_DATA_PUBADDR_OFFSET, CONFIG_DATA_PUBADDR_LEN, bdaddr); if(ret){ /*PRINTF(''Setting BD_ADDR failed.\n''); */ } /* Init BlueNRG GATT layer */ ret = aci_gatt_init(); if(ret){ } /* Init BlueNRG GAP layer as peripheral */ ret = aci_gap_init(GAP_PERIPHERAL_ROLE, &service_handle, &dev_name_char_handle, &appearance_char_handle); if(ret != BLE_STATUS_SUCCESS){ } ret = aci_gatt_update_char_value(service_handle, dev_name_char_handle, 0, strlen(name), (uint8_t *)name); if(ret){ } ret = aci_gap_set_auth_requirement(MITM_PROTECTION_REQUIRED, OOB_AUTH_DATA_ABSENT, NULL, 7, 16, USE_FIXED_PIN_FOR_PAIRING, 123456, BONDING); if (ret == BLE_STATUS_SUC

Posted on September 28, 2015 at 11:32Goodmorning, We bought the STEVAL-IDW001V1 evaluation board and the STEVAL-PCC018V1 module to connect it to the pc; the STEVAL-IDW001V1 it's already updated to the last release FW 3.4.We need to receive some data from a smartphone on a microcontroller connected to the wifi module, the SPWF01SA shall be the server and it shall create a local network to which any smartphone (IOS, Android, Windows) can connect.The SPWF01SA should open a socket (UDP or TCP) on a port already defined and by our app the smartphone should send data to the module.The SPWF01SA should in turn send this data (max 10 byte) to the microcontroller via UART. The smartphone should recognize the network, connect to it, open the tansmission and send data.Is there a SPWF01SA configuration to do this? Is there also an example of instruction which will make thi configuration easier to me? #spwf01sa21

Posted on October 01, 2015 at 12:44Hai,I have configured SPWF01S wifi module as miniAP andI have connected STM32F7-Disco with SPWF01S through UART.I am sending the command AT+S.SOCKD = <port number> to the wifi module and it is ready for listening.Now I have connected my  mac to the wifi module and I am sending a string to it.I would like to access the buffer where this string will be stored on the wifi module.Question.1. where the strings will be stored in the SPWF01S module during Transmit and Receive.2. How I can access it ? #spwf01s-wifi

Posted on May 12, 2015 at 11:08Hello,I want to use a BlueNRG as HCI device. I�ve used the ACI Command Write_Config_Data to set a public address (0xaa, 0x00, 0x00, 0xE1, 0x80, 0x02). I use the HCI command �LE Set Advertising Data Command� and finally use the HCI command �LE Set Advertise Enable Command�.All that commands report successfully execution but when using a generic BLE Client (like BLExplr on iOS), I can not see any advertising Device. What am I�m missing? I don�t want to use the GATT/ATT stack of the BlueNRG, because I want to use BlueNRG to test my own GATT stack.Thank you for every tipp or comment on this.Cheers,Torsten #bluenrg-advertizing

Posted on October 01, 2015 at 11:52Hi there, i am running the BlueNRG with multiple services, such as a proximity service, a performance test service and an application service. The proximity service has 2 characteristics, the PerformanceTestService 3 and the AplicationService 13, where the last characteristic (message) is of type string with a variable size. The ApplicationService once run alone with the maximum string size. After adding another service, the BlueNRG responded with BLE_OUT_OF_MEMORY. I fixed this by reducing the maximum char value size of my ApplicationService's message characteristic to 128, but soon after adding the next service, the problem appeared again. I would like to know:Is there a GATT limitation on the board or a maximum GATT stacksize ? I have read the documentation, however I may have overread it. Thank you for your answers :) #bluenrg-ble-gatt

Posted on September 28, 2015 at 15:16Hi,I've been searching for an ST forum related to stw81200 (rf synthesizer), but can't find any. Does anyone know where to post?Thanks.

Posted on September 21, 2015 at 22:15Hello,I am facing similar issues with limited resources on higher data rates using notification packets of 20 bytes. Were you able to find a workaround for this ? Can someone from ST provide some insight on this?

Posted on September 18, 2015 at 09:16Hello Maurizio,first of all the answers:1) The way we can measure it can be getting:- a TX node with a TX signal output on GPIO - a RX node with a SYNC detected signal output on GPIO- a scopeThe time delay can be measured as the event when the last bit of sync is put on the air and the SYNC detected signal is asserted (propagation time of these signals in the silicon is almost negligible). Time between them is 13 bits time about.2) No. For sure the device must be in RX state3) Yes, it depends on the first word that matches one of the possible patterns admitted contemplating errors. So it is definitely not predictable.4) It is 13bits time. Anyway, we are talking about signals propagating at the speed of light (this means that we'd have ~3us for 1 km!).Even if You have an extremely fine timing measurement Your measure could be disturbed by ray scattering or by the jitter on the XTAL used to supply the RF (that is the clock reference fo

Posted on September 17, 2015 at 10:29Looking at the examples provided with X-NUCLEO-IDB04R1 I found it difficult to understand all the layers and protocols. If I want to establish connection with a device and send/receive some data - what function should I use? what files should I look? Is there a manual explaining how high level functions work and what functions I need to perform different tasks?

Posted on September 15, 2015 at 12:44Hi, I tried to connect to a wireless network, which do not broadcast its SSID, with the above mentioned module. I tried as usual: AT+S.SCAN AT+S.SSIDTXT=TestAP AT+S.SCFG=wifi_wpa_psk_text,Test123 AT+S.SCFG=wifi_priv_mode,2 AT+S.SCFG=wifi_mode,1 AT&W AT+CFUN=1 The response after the reset is just the scanning procedure...+WIND:2:Reset +WIND:1:Poweron (150410-c2e37a3-SPWF02S) +WIND:13:ST SPWF01SA2 IWM: Copyright (c) 2012-2014 STMicroelectronics... +WIND:3:Watchdog Running +WIND:46:WPA: Crunching PSK... +WIND:0:Console active +WIND:32:WiFi Hardware Started +WIND:21:WiFi Scanning +WIND:35:WiFi Scan Complete (0x0) Is there something I've to add to the configuration to get it done? Thanks

Posted on September 14, 2015 at 14:34Hello,On the same topic, I'd like to have some clarifactions, seeing I have difficulties finding information on the different Stack mode (specially mode 3 & 4).Are the following configurations possible with BlueNRG-MS ?1) Device(BlueNRG-MS) connected to 1 master, advertising and scanning still active.2) Device(BlueNRG-MS) connected simultaneously to 2 masters, scanning still active (i.e. able to received advertising data from other devices)3) Device(BlueNRG-MS) connected simultaneously to 1 master and 1 slaveThank you

Posted on September 11, 2015 at 18:11Hello every, I would like to understand how SQI works into SPIRIT1 to evaluate if it can be used to calculate time of fligth (ToF) for distance measurement beween two end node.To have a best ToF measure SQI value must be directed connected on one GPIOx by internal multiplex to avoid any time delay for internal state machine and SYNC matching response.Questions are:1) How much is the time delay beween RX SYNC detection by SQI correlation and output on GPIO? 2) Is signal SQI response time affected by state machine status or not?3) If I set SQI_THR >0 mean that there is a jitter in the SQI response depending on how my bit are wrong in the incoming SYNC WORD packet?4) If I set SQI_THR = 0 how much is the delay between end of SYNC word and SQI assert on GPIO?Any response will be appreciate.Maurizio Brignoli #spirit1-sqi-response-time---tof

Posted on September 10, 2015 at 07:46Hi Salvatore, I faced same issue on BlueNRG-MS. I found LL_WITHOUT_HOST in UM1865, then I set 1 to LL_WITHOUT_HOST, after reset and before any other commands. However, I not yet got any ACL data. Please let me know any advice. Best regards, Hasegawa

Posted on September 08, 2015 at 15:52Hello,I'm trying to POST some JSON data to my server but it seems I'm having a problem because the post data is comma delimited just like the POST command arguments.  I have already tried to escape the character with ''\,'' but it does not work.  Is there a special escape character for using commas inside the data of a POST?Pat #http-post

Posted on August 31, 2015 at 19:13Hi everybody, I'm evaluating the SPWF01SA and I'm wondering if there is a minimum delay between messages useful to determine the end of a transmission, ex. between the response to a command and a following WIND? Thanks Paolo

Posted on August 28, 2015 at 11:39Hi , when i using AT+S.SCAN the resulting 1: BSS C0: 040404040404040404040404040404+WIND:8:Hard Fault:Console1: r0 34303448 , r1 20000E8Cwhat is the problem and how to solve it if possible?

Posted on August 25, 2015 at 08:59Hello, again, I perform a simple loop at one device configured WITHOUT LDCR mode and WITHOUT Timeout Mode, permanently /but not PERSISTENT/ stay on RX. At regular intervals /5sec/ SPIRIT going to transmit a packet of 50 bytes /Basic Protocol/. The other device receive that packet and whole system working, but at iregular intervals /20-30 min to couple of hours/ system stops working. At Device who transmit, I make a Loop like that: - Fill TX FIFO, then SABORT, then LOCKTX, then TX, and Set FlagTX on MCU. Then if FlagTX is 1, I poll IRQ[0] Reg at 0xfd at SPIRIT, and wait for TX sent Interrupt. If they appear, I'm going from Tx to RX /SABORT, then Lock RX, then RX/, of course I clear FlagTX on MCU, and stay waiting for next 5sec interval. When system stop working, I see that My FlagTX is ''1'', so I think, there is missed IRQ TXsent. Is that possible? And more generally, at the datasheet there is only a short description of IRQ's, but there is no descrip
