Dear Engineer,
Hello! I’m developing a custom PCB that integrates the AWR2243 radar sensor and includes a UART interface for wireless data transfer through a Bluetooth module. The main goal is to send basic configuration and debug data wirelessly from the radar board to a laptop or mobile device.
However, I’m encountering issues with data transmission stability. The radar system initializes correctly, but the UART output becomes unstable once connected to the Bluetooth module. The module pairs successfully, but I frequently see corrupted or missing data bytes.
Here are my main questions:
-
Could this be related to the radar’s signal timing or the UART voltage levels on the PCB (currently at 3.3V logic)?
-
Do I need to buffer or isolate the UART lines between the radar SoC and the Bluetooth module to avoid signal distortion?
-
Has anyone successfully interfaced the HC-05 Bluetooth Module or HC-06 with the AWR2243 for wireless debugging? If so, what baud rate and configuration worked best for stable transmission?
