We're using a BLE module with our Arduino Nano for a school project. We would like to perform two things: First, is disable the BLE from using the TX/RX lines so that we can program the Nano with our USB (TX and RX are shared by the USB port for programming). We were thinking of adding a DPST switch between Nano and BLE but a software solution would be cooler. Second, we want to shut down the BLE's transmitter to save every little drop of battery energy. We don't see a function in the lib for doing that. Our current idea is to not send it any data but that seems like it would still transmit. Would appreciate any suggestions regarding these two items and thanks in advance.
