Interface and connectivity ICs

Posted on April 04, 2018 at 06:56Hi,First of all, sorry for the lengthy message.We are developing a 433 MHz transceiver using SPIRIT1. We were able to run 'SDK_BasicGenreic_A' program provided with the development kit on 'STEVAL-IKR002V3D' daughter-board. But, when we are trying to dump the same code in our own board, SPIRIT1 is unable to enter into 'LOCK' state. We have ensured that the following conditions are met:1) SPI communication is working (able to read and write to SPIRIT1 registers)2) 50 MHz sinusoidal signal got generated at crystal's terminals (observed using DSO)3) SPIRIT1 is entering into 'STANDBY' and 'READY' modes (checked MC_STATE1_BASE register status)We have compared all the register values at various stages of the code with those of the reference board's registers. All of them are exactly the same, except for '0xB2', which should have been changed to 0xCA, but still is 0x42 (default value).The major difference is occurring, when we executed

Posted on April 03, 2018 at 18:43Hi ST team,Looking over the device datasheet, I had expected to see maximum current consumption at least under TX and RX conditions so I can design power management appropriately.  When this information is missing, I typically look for a maximum ICC specification as the next best point of reference but that's missing as well.  Has there been any testing or is there a maximum ICC by device design to which I can design my power management solution?Second item:HSE and LSE signals;  I found a post at https://community.st.com/0D50X00009XkeJJSAZ  that says to ignore these pins and float.  The X-NUCLEO board ties these to a crystal and RTC respectively.  What purpose do these serve?  Also, if these are inputs, shouldn't these be tied to a logic level to prevent oscillating inputs?null

Posted on March 28, 2018 at 17:00I have been able to use the File Print (AT+S.FSP) in some test situations, but now that I'm using it for real I'm not getting any results.When I was performing my feasibility tests I was printing sections from within a small text file located in the Application volume.When i try to do a similar task with a large text or binary file that is on the User Volume the command just hangs with no reply.I can see from the FSL command that the file is present with the 'E' prefix indicating user volume.Interestingly the AT+S.FSP command when echoed back is not terminated with 0x0D 0x0A as I would have expected (from seeing other command replied) but with 0x0D 0x00The binary file is 173Kb in size and the text file was 486Kb in case there is a file limit issue with the command.The command content I was sending was  AT+S.FSP=/firmware.hex,0,256It does not matter if I try to list the entire file using AT+S.FSP=/firmware.hex,, as this also fails in the

Posted on March 15, 2018 at 07:44Hello and good day!I'm attempting to use the SPWF01SA module with an STM32F0 microcontroller to post some data onto a remote web server. I have come to understand that the  AT+S.HTTPPOST command can only post form data. However, my requirement is to post a JSON packet instead of form data. So, I'm using the  AT+S.HTTPREQ command to send a custom POST request. However, the problem I'm facing is that I'm receiving only '\r' as response from the SPWF01SA module, on executing the AT+S.HTTPREQ command.To walk through my steps, I'm first connecting to a WiFi network using all relevant commands, and am able to successfully receive the 'WIND:24' message from the module. After this, I'm sending the AT+S.HTTPREQ command to the module in the following format:AT+S.HTTPREQ=https://community.st.com/external-link.jspa?url=https%3A%2F%2Fwww.xxxx.com%2C80%2C1000%5CrPOST /gaiahardsurveytest/v2/getHardSurve

Posted on March 29, 2018 at 19:19Hello,I'm trying to figure out whether it is possible or not to upgrade the firmware of a host processor connected to BlueNRG-MS.From this http://www.st.com/en/embedded-software/st-blue-dfu.html it seems possible:'The ST BlueDFU app allows WeSU (STEVAL-WESU1) boards to receive firmware images over-the-air from a smartphone and write them to the STM32L151 Flash memory.'There is even an application note dedicated to this : http://www.st.com/content/ccc/resource/technical/document/application_note/09/45/83/e0/7d/67/46/2c/DM00115333.pdf/files/DM00115333.pdf/jcr:content/translations/en.DM00115333.pdfBut when digging in the code of STEVAL-WESU1 or X-CUBE-BLE I couldn't find where and how it is implemented.I would like to adapt it to make the firmware of the module CMWX1ZZABZ-091 upgradeable from ble.By the way I couldn't find the source code of ST_BLUE_DFU app. Is it possible to get it somewhere? The only feature I want to use from bluetooth is the OTA.Thank

Posted on March 28, 2018 at 17:09I'm looking at the SPWF04 training course which is very good by the way, but it mentions I should refer to 'SPWF04S Power management Application Notes' for more details on the Low power modes.Been unable to find this, anyone got a working link for it or other resources which describe the actual functions of all of the low power variables:What I'm trying to find out is...wifi_powersave  (what is the difference between PS and Fast-PS)wifi_operational_mode (what is the differencwifi_listene between operational mode and quiescent mode)wifi_beacon_wakeup (what is the difference from using values 1, 10, 100, 1000? with wifi_listen_interval set to 0 or 1 ?)

Posted on March 28, 2018 at 13:58Hi!My SPIRIT1 code is not working properly and I found confusing the description of the INTERRUPT_MASK and INTERRUPT_STATUS registers in the SPIRIT1 datasheet (rev 10, Oct 2016). In the registers description both MASK[3:0] and STATUS[3:0] registers refer to Table 36. For me that means setting bit 6 in MASK[0] register is flagged in bit 6 of STATUS[0] register.However, in the Spirit1 library provided by ST, in the SPIRIT_Regs.h file, the relation is reversed, MASK[0] is reflected in STATUS[3].  Which one is true?I also have a strange problem, when reading the 4 IRQ_STATUS register content. I initially thought that if I set a bit in MASK (and the others are all zeroes) then in the STATUS register only that bit will flag if the event occurs. However when I read the STATUS registers I get other bits set indicating that other events are also occured. Is that a normal behaviour?Thank you!#spirit1

Posted on July 26, 2016 at 19:08I am consistently getting this error (+WIND:5:WiFi Hardware Failure:5) and I don't understand why? It is a pain because the module keeps having to be reset and it is impossible to communicate on a socket since this keeps happening. Any suggestions? #spwf01sa #spwf01sa.11 #+wind:5

Posted on February 22, 2018 at 21:28 HI, I try to get mySPWF04SAworking with micropython only. 1) I want to be able to connect to my router and send information on MQTT when connected. I have set the console_enables=2 and python_script=myscript.py in my variables. Here my script to test: from network import WLAN from pyb import LED w = WLAN(WLAN.STA) l = LED(1) l.off() MySsid = 'MySSID' print('INIT') w.init(mode=WLAN.STA, ssid=MySsid, auth=(WLAN.WPA2, 'MYPassword')) if w.isconnected(): print('connected'); l.on() print(w.ifconfig()) print('END')�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�? If I run this script with REPL, the connection is not working bu I see my traces. If I run the script with the GPIO8 HIGH and reset the board, I don't see any traces on the uart. Is it possible to have the traces on the uart with only the upython working ? 2) When I do a scan with the AT command, AT+S.SCAN=d, I see all the network available on the output. If I do the same t

Posted on March 20, 2018 at 15:26Hello,Having connected two bluenrg-1 devices, if I send a new update value from the slave to the master, is there any way of receiving a confirmation from the master to the slave when I send that new value to know if the master has receive the update correctly.Thank you

Posted on December 08, 2017 at 12:33Hi,We are able communicate to SPBT3.0DP2 module through UART. we are interested in downloading the new firmware to the Bluetooth module and hence we followed the steps given in the document ''SPBT3.0DPx BT moduleFirmware Update Procedure,Revision 1.0''. But we are unable to download the Firmware.  We followed Below steps.* Connect the SPBT3.0DP2 to PC through UART. press reset. The response was received with Bluetooth address. and communication was done between BTterm app and PC hyper terminal.* switch off the Device.* Now Connect BOOT0 pin to 1.8V supply. and connect UART lines to PC.       Note: *Since flow control is none not using RTS and CTS  pins, Pins are left floating.                * UART to USB converter is used. the Prolific UART  to USB Converter is used.* Power on the Board. press Reset Button.* Open software ''Demons

Posted on March 08, 2018 at 17:26Hello all, I am having a problems to update some values on the master, I am using bluenrg-1 I have one device working as a master and other as a slave. The slave has a button, I have both connected and every time I press the button on the slave  the function aci_gatt_update_char_value() is called containing a value, I have on the slave that configuration:aci_gatt_add_char( Service_Handle, UUID_TYPE_128, &char_uuid, CHAR_VALUE_LENGTH,CHAR_PROP_READ|CHAR_PROP_NOTIFY, ATTR_PERMISSION_NONE, GATT_DONT_NOTIFY_EVENTS, ENCRYPTION_KEY_SIZE, ATT_HAS_FIXED_LENGTH, &CharHandle);the master is discovering the service and characteristic from the slave. Do I need to do something more or in a different manner? Which event function will be call on the master?I can read the values from the master  requesting the value every x time once both are connected but I would like to received the value on the master just the button is pressed. Than

Posted on March 22, 2018 at 21:56Hi, We are evaluating the use of the BT Module SPBT3.0DP1 on one of our devices.We are trying to configure the PIN to connect to a legacy device, that already has a predetermined PIN code that uses letters (lower and upper case)Unfortunately, the current Firmware on the module cannot setup capital letters as PIN for Bluetooth pairing on SPBT3.0DP1 BT Mod. The current firmware converts all letters to lower case, and therefore, the PIN doesn't match and cannot connect to the legacy device.

Posted on March 15, 2018 at 15:57Hello,I'm currently evaluating the S2LP radio chip on an FKI868V1 and I'm trying to reach sensitivity marks described in the datasheet.I'm having trouble getting the kind of sensitivity expected when testing at 300 bps data rate.  The exception rate of packets is less than it is at 1.2 kbps and I can't understand why.Can someone please help me achieve better results at the lower data rate?-Adamz#s2-lp

Posted on March 19, 2018 at 11:41I'm trying eval board with SPBTLE-1S module. I'm using BlueNRG-1 Navigator v 2.6.0. If I flash any demo application, no BLE service can be discovered on the phone (Nexus 5X, Android 7.1.1.)E.g. BLE Sensor demo - DL3 shorty blinks after reset, then BL1 slightly flashes, so the chip is doing something, but no RF signal. (Previous chip TI CC2540 has communicated correctly, with the same phone.)Have I missed something or is the chip broken? 

Posted on February 08, 2018 at 20:22Hi everybody!The current datasheet (https://community.st.com/external-link.jspa?url=http%3A%2F%2Fwww.st.com%2Fcontent%2Fccc%2Fresource%2Ftechnical%2Fdocument%2Fdatasheet%2Fgroup3%2Fc4%2F02%2Fe5%2F87%2F1c%2Fd2%2F4f%2Ff8%2FDM00328568%2Ffiles%2FDM00328568.pdf%2Fjcr%3Acontent%2Ftranslations%2Fen.DM00328568.pdf) does not give any indication to which direction that the LEDs should be going other than the name says LED Drive: module running, LED Drive: Wi-Fi Link Up, and LED Drive: power Up. This may indicate that the pin should source the LED and the reference schematic (http://www.st.com/content/ccc/resource/technical/document/data_brief/group1/f4/06/e8/8b/99/10/4d/b4/DM00375570/files/DM00375570.pdf/jcr:content/translations/en.DM00375570.pdf) also shows that the pin is sourcing the LED but they do not blink when that is the case. The LEDs only seem active when the WiFi module is sinking from the LED. Is this the proper way?Thank for the help!

Posted on March 10, 2018 at 19:01Hello! I am trying to setup BlueNRG. It's not discoverable at all. I didn't see any packets i sniffer from it. But let me start from the beginning.When I just started, it didn't work (was undiscoverable). I found that IFR programmed for 16MHz quartz use, however I have 16MHz. So, I tried to upload IFR, but it didn't work. (aci_error).Then I tried to upgrade firmware, but there are a lot of problems:First: firmware has wery unconvinient format, which is impossible to use without BlueNRG GUI (I cannot use it becouse I use custom mcu connection). The file is looks like 32 bit numbers without delimiters (20003000).I converted it into normal values and then succesfully upploaded to the BlueNRG.When I read IFR I discovered, that all register groups of 4 bytes are mirrored:0x02,0x3A,0x5C,0x02 //according to the GUI it shuld be like that, however0x02,0x5C,0x3A,0x02 //it was like that.So, I checked firmware and found, that all IFR part (and may b
