Resolved! Test software for RF test specified in AN5796 - STM32WL Series RF Bench
Hello,I would like to perform a LoRa Radio tests described in AN5796 - STM32WL Series RF Bench, but I do not find the needed files. So could you please share a link to firmware(STM32WL...) and software(python script and RSSMBV100 waveform).Thanks
Resolved! BLE OTA software options
According to AN5247 I can use ST BLE Sensor to perform a BLE OTA firmware update. I've added the reboot characteristic to my design, but how can I get ST BLE Sensor to recognize my custom board? There appears to be an option to add a new design, but ...
Resolved! Porting the Ble_ota example
I have a board based on the same chip as the ble_ota example. When I try to run this code on my board I'm finding that it immediately crashes. The crash happens before the debugger even hits the first line. I'm assuming this is something simple, mayb...
STM32WB55CG I2C MASTER COMMUNICATION FAILURE
Hi,I'm trying to read battery information from a BMS chip (I2C slave) via I2C. And I also tried to capture the clock signal on SCL with scope but it failed. This chip is already used in our other project with another MCU. This is my first time to...
Bootloader not working on STM32WB5MMG
Hi, I have a product with 2 microcontrollers on the same PCB(running independently). One is STM32G030 and other is STM32WB5MMG(ble module containing STM32WB55). I enabled internal bootloader(via option bits configuration) for both the microcontrolelr...
Resolved! Low Throughput on STM32WB1MMC
I have setup a client and server with two STM32WB1MMCs and have the server periodically send data based on a frequency stated by the client. My payloads are 10 bytes long and are incrementing values for me to keep track of any losses. I am finding th...
