Problems receiving uart data

by alexstarra on Wed Mar 24, 2021 3:02 pm

Hi, I've been using the Bleuart example provided with the nrf52832 Feather connected with the Bluefruit LE mobile app and whenever I attempt to send data through the serial monitor cannot read it properly. I have attached an example, I am receiving new data however it appears as a question mark.

This sure looks like a baudrate mismatch with the Arduino IDE serial console setting (bottom right) and whatever the baud the code is set to. Which BLE UART example are you running? We are using 115,200 based on this guide:
