Posted on March 01, 2017 at 18:02Hello,I have some trouble trying to use SSI tags in custom html page. I can't manage to make it usable...Let me explain a bit:(All the following is hardcoded)First, I create a file :AT+S.FSC=/test.shtml,100\r?And put some content into :AT+S.FSA=/test.shtml,100\rFollowed by raw data :'<html>''<head><title>Input Demo</title></head>''<body>''<p>Input from Host: <!--&sharpinput--></p>''</body>''</html>'Until here, everything is all right.But if i load my page, the specified timeout (2s) is triggered and the content of the SSI tag is :WebServer currently busy. Please try again later.I understand that my SSI tag <!--input--> is never replaced because i never see any message on UART link before the end of the timeout; so i can't put any data over UART.In fact, i receive a complete  +WIND56 message (I dump every byte received from uart rx int) when page loading has ended :+WIND:56

Posted on February 23, 2017 at 11:07 Hi, Using the SPWF01SA module, i managed to connect to all of the networks i found here, except one. I probably got the configuration wrong, but i can't find where's the error. To my knoweledge, the only difference this network has from the other networks (to which i can succesfuly connect) is that it gives out ips in the 0.x range, instead of the usual 0.x one. I tried disabling the dhcp and assigning the gateway ip and dns ip manually, also setting a static ip (i used 50 or something like that), to no avail. I should also mention that both my laptop and phone can connect to this network without problem. Here's the configuration i am using: # Dumping All Configuration Keys: # nv_manuf = ST # nv_model = SPWF01SA1 # nv_serial = 3514D04763 # nv_wifi_macaddr = 00:80:E1:B4:7D:1F # blink_led = 0 # wind_off_low = 0x00000000 # wind_off_medium = 0x00000000 # wind_off_high = 0x00000000 # user_desc = anonymous # escape_seq = at+s. # localecho1 = 0 # con

Posted on February 28, 2017 at 16:22Hi,I am working on Sensortile kit with the BlueNRG-MS radio.As per ST document PM0237 section 3.3, pg 55/99, following commands are used to add custom service to BLE device : //Add the service with service_uuid 128bits UUIDaci_gatt_add_serv(UUID_TYPE_128, service_uuid, PRIMARY_SERVICE,7,&ServHandle);//Add the characteristic with charUuid_1 128bits UUIDaci_gatt_add_char(ServHandle, UUID_TYPE_128, charUuid_1, 20,CHAR_PROP_NOTIFY, ATTR_PERMISSION_NONE, 0,16, 1, &CharHandle_1);//Add the characteristic with charUuid_2 128bits UUIDaci_gatt_add_char(ServHandle, UUID_TYPE_128, charUuid_2, 20,CHAR_PROP_WRITE|CHAR_PROP_WRITE_WITHOUT_RESP, ATTR_PERMISSION_NONE,GATT_NOTIFY_ATTRIBUTE_WRITE,16, 1, &CharHandle_2);In above 7 indicates the maximum number of attribute records that can be added to this service. However, as per my understanding BlueNRG-MS always adds 6 mandatory attribute records in any custom service. So for above example, the maximum numb

Posted on February 23, 2017 at 14:35I have a BlueNRG IDB005V1D board which is connected to its motherboard. I am trying to install firmware onto the STM32L151RBT6 uC on the motherboard but when I am prompted to enter DFU mode there is no LED flashing orange, and and the attempted flash fails.I tried using the STM32 ST-LINK Utility also to load the DFU_Bootlader.hex but this says that there was no ST-Link device detected. The ST-Link connector that I use does work on another board.Are there any suggestions as to how I can flash the uC? Thank you ,cod

Posted on February 18, 2017 at 00:48Hi,My BlueNRG-MS, running 7.2c, acts both as a central and a peripheral (mode 4). How should I select the advertizing min and max intervals for the peripheral as well as the connection min and max intervals for the central? There seem to be a relationship between them, but I'm not sure I understand it.I'm trying to get the minimal connection interval for the central role, while ensuring proper connectivity for the peripheral.LE_Scan_Interval and LE_Scan_Window seems also to come into play...Right now, I'm testing different values through trial and error, but if there is a mathematical relationship between those, I'd like to know it.Thanks!#bluenrg-ms

Posted on February 23, 2017 at 16:21I try to write to a characteristic on a remote device, BlueNRG-MS works as peripheral client. I call aci_gatt_write_charac_value() and it returns SUCCESS. But then EVT_BLUE_GATT_PROCEDURE_COMPLETE comes and it is sometimes 0x00 (BLE_STATUS_SUCCESS) and sometimes it's 0x41 (BLE_STATUS_FAILED). What could be the reason and how to solve this?

Posted on February 23, 2017 at 22:04Hello I'm using SPWF01SA wifi module. When I do AT+S.SCAN all the available networks around are listed except the open ones. I can see every password protected networks (WPA2) but the open networks are not even seen by the module. Is there any way to list and connect to a non password protected network? Thank you very much.

Posted on February 23, 2017 at 18:39Hello I am using BlueNRG-ms and have a characteristic that is 52 bytes.However when the client reads it they only get the first 20 something bytes, the rest dont get transfered. Both creating the characteristic and updating its value is successfull according to event complete parameters.When i did this using the BlueNRG GUI, with the same size and same data it worked...Char setup:uint8_t data[] = {    HIDServiceHandle[0], HIDServiceHandle[1], //Handle of the service to which the characteristic has to be added    UUID16BIT, //0x01: 16-bit UUID     0x4b, 0x2a, //UUID     0x34, 0x00, //Maximum length of the characteristic value     PROPERTY_READ, //Bitwise OR values of Characteristic Properties     0x00, //0x00: ATTR_PERMISSION_NONE     0x01, //0x01: GATT_SERVER_ATTR_WRITE The application will be notified when a client writes to this attribute     0x10, //The minimum encryp

Posted on February 23, 2017 at 14:49Hi everyone, I want to implement a very simple file transfer via BLE from my SensorTile to a remote device.I need to edit the BlueMicrosystem2 V2.2.0 firmware in order to add a new characteristic: such a characteristic should read a file from the SD card and send them from the SensorTile to the remote device (a kind of reverse FOTA).Reading the file is not a problem, but I have no idea where to start from for developing the service which provides this file upload characteristic.Can you point out a code snippet or where, in the firmware code, there is a similar GATT service that may be adapted easily to me needs. Tnx!Andrea#ble #bluenrg #sensor-tile

Posted on February 22, 2017 at 17:17Hi, i began evaluating the SPWF01SA module, and i managed to make it work with most of the WPA2- personal authenticated networks. I was wondering though, is it possible for the module to join a WPA-enterprise authenticated network? (aka a network that requires user+pass to authenticate)Thank you,Matteo#wifi #spwf01sa

Posted on February 22, 2017 at 11:29Hi,We use SPWF01SC module in customer product. Device will be used in complex WiFi environment.We tried to test WLAN connectivity in 802.11b, g and n setups in order to determine which one will better serve our needs in real world conditions.We were trying to limit connectivity to 802.11g only by disabling 802.11b,n using wifi_opr_rate_mask parameter.It seems this limitation works properly in other combinations, but mask 0x3FC0, 11 1111 1100 0000b (802.11g only) does not work for us.Discovery simply does not find any networks, when we apply this operating rate mask.Base station (router) seems to work properly with other devices in 802.11g network.wifi_ht_mode set to 1.Is there any bug or a misunderstanding on our side?#ieee-802.11 #wi-fi

Posted on January 10, 2016 at 15:06I'm developing a custom firmware for SP1ML but I miss important info regarding connections between the STM32L151RB and the SPIRIT chips. Analysing the firmware loaded on the SP1ML, I understood that:    PA5     ------> SPI1_SCK    PA6     ------> SPI1_MISO    PA4     ------> SPI1_NSS    PA7     ------> SPI1_MOSI     PA1     ------> SPIRIT_SDNBut I fail to understand how the 4 different IRQ pins of the SPIRIT are connected to the STM32L151RB. I guess that an IRQ is connected to PC4 but I don't know the corresponding IRQ line on the SPIRIT.Regards,Dario #sp1ml-spirit1-stm32l151rb

Posted on February 21, 2017 at 21:57Hello, I am using a BlueNRG-ms (IDB05A1) flashed to latest fw 7.2c trying to develop a HID compliant mouse for Windows.However when pairing with windows using only the basic GATT and GAP(no other services or changes) from the BlueNRG GUI there are some problems, Windows says:Device (0x280E1003C2A) is not Compliant with the Bluetooth Core Specification: previous attribute was a (Characteristic), current attribute is a (Descriptor).Is this a bug or is Windows wrong? BlueNRG-ms page states:'The BlueNRG-MS is a very low power Bluetooth low energy (BLE) single-mode network processor, compliant with Bluetooth specification v4.1.'Is this a cause for concern?#stm32 #bluenrg-ms #windows #idb05a1 #hid #bluetooth #ble

Posted on December 28, 2016 at 09:02Can anyone help me out on this issue? I have taken too much time on this...en.fp-sns_flight1_firmware is the best referencing project which provides good example of pairing procedure and security issue on peripheral side..But I can noy find good example for pairing procedure handling on central side which requires encypted physical link. I followed a programme guide to implement pairing handling and security configuration but I always get pairing failure event.#bluenrg-bluenrg-ms-central-encrypted-physical-link

Posted on December 23, 2016 at 10:31 Can anyone provide sample project ofBlueNRG-MS in central role where security linking is required? In sample project 'STM32CubeExpansion_BLE1_V2.7.0\Projects\Multi\Applications\SampleAppThT', it includes central role but it does not require bonding/pairing. I also checked 'OSXSmartConnPS\OSXSmartConnPS_V1.5.0\Projects\Multi\Applications\Profiles_Central\MDK-ARM\STM32L476RG-Nucleo',which does has central profile framework but no source code of this framework is provided. I use x-Nucleo-IDB05A1 kit to send pairing request toWesu kit. x-Nucleo-IDB05A1 kit is set to central role whileWesu reference kit is coming with peripheral role naturally. Both sides are set to use fixed PIN code 1234 After connection is made, x-Nucleo-IDB05A1 kit sends pairing request to Wesu kit by calling: ret = aci_gap_send_pairing_request(connection_handle,0); Immediately, x-Nucleo-IDB05A1 gets an event of pairing completion with 0x02 which says pairing has just faile

Posted on February 19, 2017 at 07:30AN4630 ('PCB design guidelines for the BlueNRG and BlueNRG-MS devices') shows a schematic and PCB layout example for a discrete balun - what I didn't find are actual values for the components (L2, L3, ..., C9, C10, ...)Are there recommendations for these components available somewhere?ThanksMichael

Posted on February 17, 2017 at 21:15Hello,I am doing some embedded programming on a stm32-nucleo board with a 0DB05A1 BLE shield. I am trying to make a HOGP perihperal (HID over BLE). When I try to pair my device with windows it fails with 'Driver error'. I'm guessing the problem is on my side. I want the bare minimum to be able to use the peripheral as a Boot Mouse.Currently I have the following services and characteristics.The default GATT from GATT_initThe defualt GAP with the following: PERIPHERAL, PRIVACY_DISABLEHID Service   Report map characteristic       - Read   Protocol mode characteristic   - Read, Write w/o response   HID Information characteristic - Read   HID control point characteristic - Write w/o response   Boot mouse input report char   - Notify, Read      Client characteristic configurationBattery S

Posted on February 05, 2017 at 20:27Hi i want to use SPWF01SA wifi module, but i'm confused about connections.  I want to control SPWF01S with another mcu and in my schematic i've connected only rx,tx, vcc and gnd also one connector like jtag. But i did not understand how to program module ? My jtag connections right ?  In SPWF01SA with nucleo board schematics, there is a connector like a jtag. (Below en.x-nucleo-idw01m1_schematic.pdf) I need help about connections with my mcu and also RTS and CTS pins. I write details below pictures. My design is SPWF_wifi.PDF.  I'm sure that, there are forgotten connections. With warmest regards.#module #spwf01sa #wifi

Posted on February 15, 2017 at 16:04Hello,I downloaded the BlueNRG-1 Devkit, which has a project with a hid peripheral, however only the .h file is included the other part is a .lib file that i can not view, where can i find the source code for this lib?#bluenrg-1 #stm32

Posted on October 05, 2015 at 09:57Hi, Is it possible to update firmware from host processor over UART without any windows utilities like flash loader? We use FreeRTOS in our product, so, FW update protocol description or any clues are welcome.

Posted on February 14, 2017 at 11:35Hi,I'm using the BlueNRG-MS chipset. As far as I've understood, the connection interval is set through 'aci_gap_set_discoverable' and if the related arguments of the function (SlaveConnIntervMin and SlaveConnIntervMax) are 0, it is set to 7.5 ms (as for BLE standard), otherwise it is set using multiples of 1.25 ms. Which is the minimum value which can be set? Can the connection interval be set to 1.25 ms in order to maximize throughput?Thank you,Daniele#bluenrg-ms
