Hello everyone,
We are using the STM32F103C8 connected with the Microchip RN4871 BLE module over UART1. We would like to update the firmware of the STM32 CPU over BLE but we are encountering a few issues. Our BLE module, although it works great for our application, it does not support even parity on the UART. On the other hand, the STM32F103C8's bootloader requires even parity. This incompatibility won't allow us to update the firmware over BLE. So, I would like to ask if it is possible to change parity settings on the bootloader. If not, can anyone suggest a BLE module that supports even parity and AT commands?
Thank you in advance
