Hello, We are working on a project, that uses an Xbee remote sensor, that senses LDR data and transfers data to a Xbee coordinator connected to an arduino. The arduino after sensing data, sends a remote RF command back to the remote sensor that triggers an LED. I have been experimenting the remote sensor with a USB power supply so far. Today, I thought of using a battery to power the remote sensor. I experimented with two to three NiCD batteries having 3.2 and 4.8V, by connecting it to the power supply socket in the grove board, but I see that when powered by battery there is no transmission received by the coordinator module connected to arduino. Transmission happens for a second and then stops, I set PL level to lowest for the remote sensor and checked again, it’s the same. Could you address this problem? The second issue I faced was I had a 9V duracell battery for testing, and I connected it to the power supply socket, and it so happened, after 3 to 4 seconds, I removed the battery and tries powering the xbee board again with USB, now the xbee lights doesn’t seem to turn on. May I have damaged the xbee. The USB recognizes the board, and device is not identified in XCTU. ---

The grove board is not set up to be powered via the battery connection. It sounds like you damaged the module as the Grove board if I recall does not except that high of a voltage.
