STM32 MCUs Wireless

Hi I am trying to use the AT-Slave application from icube lrwan stack on b-l072z lrwan in the IN865 band. When I give AT comand, I get AT_ERROR as response. Please help.Thanks,Mary

Is there a difference in hardware for these communication protocolls? Or is it possibile, that there will be sometime a wifi stack for the STM32WB?

Hi, recently I made a custom board with STM32WB55RGV6 but my BLE side isn't working.I used STLink to flash in the CoPro lib FW as shown in the YouTube link below.https://www.youtube.com/watch?v=AcrbUOhApd0I used the P2P_Server example for Nucleo board and verified the same code works on the Nucleo board.I used a 3GHz spectrum analyser to check on the RF pin output via direct connection but I saw nothing emitted across the whole band.I tried to read the version with STM32Programmer but all wireless FW FUS version read options are grey and no way to check on the BLE FW version loaded inside.So, I am wondering if there is anyway that I can check the loaded FW version, i.e. "stm32wb5x_BLE_Stack_full_fw" the M0 core? Even though it showed "Loaded successfully", is there anyway to double check?Thanks in advance.

I'm trying to make all of my STM32WB55 Zigbee network run on batteries. The SEDs are easier enough, but I need a solution for the coordinator.   My current plan is to disable the Zigbee radio when not in use.   What is the process to disable the Zigbee radio? I see the radio system reset bit in RCC_APB3RSTR, but that only gets me to 2.8mA idle. A complete system reset without booting CPU2 idles <1uA. Can I clone the coordinator via ZbPersistGet() and ZbStartupPersist()? It would be nice if I could restart the network and communicate with previously connected end devices.   Thanks in advance for any advice on these questions or if someone recommends a different direction to get the coordinator on batteries.    

I am a beginner with STM32 and the NUCLEO-STM32WB55 board.The preflashed demo application worked without problems. When I installed the STM32WB55 MCU package, a couple of examples were available like the BLE HRS service.I managed to import the project, compile and flash it, but nothing 'happened'. Couldn't see any advertisements, no UART debug messages, etc. Tried another one, still the same behavior. Started reading about the whole eco-system and saw that there were firmware binaries in the MCU package. Despite that the first pre-flashed project worked, I wanted to give it a try and flashed according to the release-notes:How to flash the Wireless Coprocessor Binary via USB (STM32CubeProgrammer GUI)   Inside the below procedure, the references to binaries name and install address are provided in the section Main Changes of this file.   STEP 1: Use STM32CubeProgrammer GUI   Version 2.4.0 or higher.   It gives access to Firmware Upgrade Service (FUS) (AN5185 : ST firm

Hello,I am trying to use the STM32WB55 Nucleo Pack to develop a BLE application. I am using cubeMX with the STM32Cube_FW_WB_V1.8.0 pack to generate code for the MB13355C nucleo board with STM32WB55RGV6 MCU.I have successfully set the BLE advertising settings and can read the ad with the nRF Connect app on my smartphone. But when I tried to connect my phone to the board, I couldn't get GATT services back. However the connection is successful because the card indicates to be connected as a server. Has anyone ever had this problem? And how can I solve it?Thank you for your reply!

I was wondering if it would be possible to know if adafruit’s VC0607 camera with the P-Nucleo-Wb55 board.i’m not receiving any data back from the camera and i saw that there’s other stm32 that handles jpeg multimedia that this P-Nucleo doesn’t

Hello, i'm trying to sense the temperature via ADC (DMA) and then pass it to the wireless-core M0 in order to show it on my smartphone, e.g. by using the already existing body temperature profile in the STM BLE-applications. In this existing application (also available in the workshop files) there is a running timer and simply the timer value is shown. But how can i pass the adc-buffer variable, only the M4 processor can access, to the M0 processor? I know how it works in theory, i have read the application notes but is there any example application? I think STM unfortunately does not concentrate on this topic very much..Thanks

Hello,Can someone help me?I work with STM32CubeIDE, I-CUBE-LRWAN, Import End_Node Project example, config everything to work on Class C.Device successfully join to the network, and switch to class C done appears on Serial terminal. But, when the uplink interval comes, and serial terminal showing SEND REQUEST , there is no packet comes to the gateway (monitored over Gateway dashboard from Network Server) while Class A with same hardware and Project Files on STM32CubeIDE works.Class C is needed because I need to control relay output simultaneously.I tried on SX1276, SX1272 Mbed board, with Nucleo-L073, also on B-L072Z-LRWAN1, nothing different.We use RisingHF Network Server, Nucleo Gateway and Rising HF Gateway.Thank you

I have a mesage from STM32CubeMX: "STM32CubeMX cannot load this MCU" (latest version 6.0.1)

I need to be able to install/upgrade the CoPro from CPU1.I get the FW for CPU1 and CPU2 by its system-bootloader via SPI from another STM32-MCU. Sadly FUS-commands in the System-bootloader are only supported by USB and UART. Studying AN5185, this task sounds easy a.f., however i already fail by activating CPU2:here is my current Workflow on the P-NUCLEO-WB55-Board with FUS v1.1.0 and deleted Stack: HAL_Init(); SystemClock_Config(); MX_GPIO_Init(); MX_RF_Init(); MX_RTC_Init(); MX_USART1_UART_Init();   // AN5185 1.3 How to activate FUS // Ensure Cortex®-M0+ is activated by setting C2BOOT bit in PWR_CR4 register SET_BIT(PWR->CR4, PWR_CR4_C2BOOT);   /* Ensure IPCCDBA (option bytes) points to a valid shared table information structure in SRAM2a (fill correct pointers to device information table and system table) */ // struct with 6 ptr see: AN5185 Figure6 Shared table architecture IPCCDBA_T* pIpccdba;   do { uint32_t ipccdbaOffset = LL_FLASH_GetIPCCBufferAddr

I trying to port STM32CubeExpansion_LRWAN_V1.3.1 for the evaluation board B-L475E-IOT01A2. I managed to whittle the errors down to 2. In both cases i am getting unknown type name '__RAM_FUNC'; did you mean '__ARM_FP'?in a HAL file stm32l4xx_hal_flash_ramfunc.h generated by STM32CubeIDE. What does this error mean?The crazy thing is that __RAM_FUNC gets defined in stm32l4xx_hal_def.h, and stm32l4xx_hal_def.h is included in stm32l4xx_hal_flash_ramfunc.h, but somehow the compiler fails to register this??#if defined ( __CC_ARM  ) || (defined (__ARMCC_VERSION) && (__ARMCC_VERSION >= 6010050))/* ARM Compiler V4/V5 and V6  --------------------------  RAM functions are defined using the toolchain options.  Functions that are executed in RAM should reside in a separate source module.  Using the 'Options for File' dialog you can simply change the 'Code / Const'  area of a module to a memory space in physical RAM.  Av

Hello everyone!I'm trying to setup a very basic application and currently have my LPUART Tx and Rx pins tied together. I'm able to run the following code without any issues (well, this is the core of the code with all the initializations stripped out for quick, readability purposes) :uint8_t TX1_Char = 0x01; uint8_t RX1_Char = 0x00;   int main(void) { while(1) { HAL_UART_Transmit(&hlpuart1, &TX1_Char, sizeof(TX1_Char), 100); HAL_UART_Receive_IT(&hlpuart1, &RX1_Char, 1);   RX1_Char = 0;   HAL_Delay(100); } }Obviously, all it's doing is sending TX1_Char (value of 1) to RX1_Char. Pretty straight forward. What I want to do is have it run the HAL_UART_RECEIVE_IT function from the HAL_USART_RxCpltCallback function and receive it there. So this is essentially what I'm trying to do:uint8_t TX1_Char = 0x01; uint8_t RX1_Char = 0x00; int main(void) { while(1) { HAL_UART_Transmit(&hlpuart1, &TX1_Char, sizeof(TX1_Char), 100); //HAL_UART_Receive_IT

I'm trying to understand the SAI configuration options. I would love to be able to use PDM for Audio Input, and I2S for Audio Output. Is a configuration like that possible? Or do I need to use SPDIF for Audio Out if I'm using PDM for Audio In?

HI there,I am using STM32WB55 ble as a client. but after few seconds the scanning process to connect ble server is stopped working. I want to know how can i solved this issue.Warm RegardsSarthak Malik

I have several boards with STM32WB55RE chips. In most of them chip works fine and and BLE is allright.But in a small amount of them I have unknown problem - the device can't init BLE periphery in the first cycle of UTIL_SEQ_Run( UTIL_SEQ_DEFAULT );I taked BLE functionality from the example of Heart Rate service.First of all I do initialization like in the example. Then the codeflow goes in endless cycle with UTIL_SEQ_Run( UTIL_SEQ_DEFAULT ); function.And at first cycle the code stay at UTIL_SEQ_WaitEvt(0x02) function and can't receive any response from hardware I think.Here is my my call stack:mainUTIL_SEQ_Runshci_user_evt_procAPPE_SysUserEvtRxAPP_BLE_InitSHCI_C2_BLE_Initshci_sendshci_cmd_resp_waitUTIL_SEQ_WaitEvt( 1 << CFG_IDLEEVT_SYSTEM_HCI_CMD_EVT_RSP_ID );// CFG_IDLEEVT_SYSTEM_HCI_CMD_EVT_RSP_ID = 0x01Can somebody explain what event chip waiting for?

Hello everyone,I developed a custom board based on the B-L072Z-LRWAN-1 Discovery Kit. I could flash the CMWX1ZZABZ-078 (STM32L082 + SX11276) and every function work well. The problem is in the time when trying to communicate with the PC throught USB. Before flashing the module for the first time (just connecting the pcb as it came from manufacturer), the PC does not detect it.After flashing it wit the STM32CubeIDE or the mbed online compiler, the PC detect it but it does not recognize it.I downloaded ST USB drivers from ST website but it does not fix itThe schematic and layout looks good and I designed the USB lines with 90 ohm impedance. I attached picture: I measured voltages and they are okey (5V line is 4.8v and 3V3 line is 3.31v)Does anyone could help me to find out what can be wrong?Thanks in advance,Jorge
