Verification of Crystal suitability for STM32WL design
We have a design implementing the STM32WL55/WE5.The recommended crystals on the reference designs and literature are:NX2012SA 32.768KHz EXS00A-MU00527X2NX2016SA 32MHz EXS00A-CS06465I want to verify that it is OK to use the following:For NX2016SA: EI...
Resolved! STEVAL-Proteus (STM32WB55MMG): Custom BLE application
Hello,I am trying to design a BLE custom template application. I start by following the STM32WB Bluetooth® LE - STM32CubeMX Application Conception (https://wiki.st.com/stm32mcu/wiki/Connectivity:STM32WB_BLE_STM32CubeMX) using the P-NUCLEO-WB55 board ...
Resolved! How to use aci_gatt_add_char_desc() for STM32WB BLE?
My biggest issue currently is on my external app which is connecting to the WB that it cannot get the descriptor.As I debug using BLE using LightBlue there is no descriptor in my characteristic. As I notice recently by reading again the manual there ...
Resolved! STM32 controller for IoT connectivity
is there any STM32 variant which has on chip IoT/ WiFi connectivity module. So that it can be configured and used just like USART or timers.Regards
Resolved! Where is .IOC file in FUOTA exemple for STM32WL
Hello,I'm using the exemple for FUOTA in STM32WL for single core (STM32WLE). And I would like to know where I can find the .ioc file to change the pinout confirguration of the chip.Thanks
Resolved! Why does BLE stop advertising when STM32WB enters low power mode (STOP2)?
Hello, I am trying to configure a custom board with STM32WB5MMG in STOP2 low power mode. For that, the program calls the PWR_ExitStopMode() function when a timer reaches 10 seconds and exits when EXTI0 interrupts by calling PWR_ExitStopMode(). Th...
Why does BLE become not discoverable when STM32WB goes into low power mode?
Hi,I'm trying to set a custom board with STM32WB5MMG into low power mode STOP2. For that, program calls PWR_ExitStopMode() function when a timer reaches 10 seconds and exits when EXTI0 interrupts by calling PWR_ExitStopMode().The MCU goes into and ex...
STM32 WL55JC1 UART only receiving data once
As the title suggest I only receive data once. I also tried using HAL_UART_Receive_DMA and HAL_UART_Receive_IT still got the same result (only receiving once). I'm using Teseo-LIV3FL GNSS module and I've tested it before on my ESP32 and it works as e...
LoRa synchronization point to point
Hello!I use two stm32wl55jc1 boards for a point-to-point connection via LoRa, simple, without a gateway. Everything goes well until I introduced the possibility to change the communication parameters (press a button and enter on UART). After the inpu...
Resolved! How to edit an existing .csv file in the SD card?
I want to save constant data on .csv files in an SD card. I managed to create the file, but when I call the function to edit, it seems not to recognize the end of the file to start writing. How can I do that? Or what can I do different? That's the pa...
