Resolved! STM32WB not responding to wakeup pin
Hi,Made a prototype board with a STM32WB55RGV. For testing the wake up I reduced to only UART1, incoming SYS WAKEUP PIN 4 (PA2), control LED on PB10, Serial Wire debugging. HSE/LSE present, but not used. BLE is not used, the firmware deleted, etc.If ...
Resolved! No BLE for STM32Wb5x Zigbee_BLE_Dynamic mode
Hello,I try to test the BLE on my Nucleo-STM32WB55 board.I use the v1.21.0 ST package for WB boards with BLE_Zigbee_Dyn exemple.I can use Zigbee without problems, but i never be able to use BLE. I can't discover device on ST BLE sensor classic.I uplo...
Which STM32 for me?
I am looking for a board, and think that I need someone to say that they have used it, rather than googling for it. In the immortal words of Jimi "are you experienced?" I would like to program in Ada, so the STM32 looks ideal.If at all possible, I wo...
Resolved! STM32WL5 Design review
Dear STM32 Community,I am working on a PCB design for the STM32WL5 and would like to seek confirmation regarding my design approach. Specifically, in the top layer, I have an RF signal track, and in the second layer, there is a GND plane. However, I ...
Resolved! About the radio frequency parameters and distance of WL33.
Dear ST experts.We are a module manufacturer. We have designed a module based on WL33. We have been using ST's dk board for verification. However, when we tested the distance, the original dk board was about 200 meters. With a 20dbm and -12X sensitiv...
