Hello everyone, I am exploring the feasibility of an IoT device using the combination of RC7630 and Raspberry Pi. However, I am encountering unexpected behavior. Specifically, when I boot up the RC7630 while it is connected to the Raspberry Pi via USB, unintended AT commands are being sent from the…
