STM32WBA55 How to wake-up with USART2 event in stop mode
Hi,i am using STM32WBA55 with BLE_p2pServer_ota example and want to wake-up over an USART2 event (start bit or rising edge) from stop mode. What is a good way to do this? I am using HSI16 with USART2 GPDMA1.
Resolved! Uploading firmware to STM32WLE5 via ST-LINK without access to boot pin
I'm trying my hand at a LoRa project and settled on using the STM32WLE5JC chip on Seeed studio's Wio-E5 module. I've read through the bootloader manual and Seeed studio has their own set of instructions for wiping their pre-existing code which I have...
Resolved! STM32WB15CC (B-WB1M-WPAN) cannot initilize MotionFx
I've been using B-WB1M-WPAN board with a modified example of motion service from BLE_HR_p2p_Sensor. but with IMU readings with a steval-mki217v1 shield connected with SPI. I already have the CRC checked from CubeMX generation. So far I have been ab...
Resolved! STM32WB05KZ POWER ANTENNA modification
Hello For the Nucleo STM32WB05KZ board, the transmission power is normally 0 dBm by default (it can go up to 8 dBm). Is it possible to modify the transmission power according to my needs, for example to 3 or 4 dBm, using STM32CubeProgrammer or ano...
