I am using two UartSBee V4 together with Xbee Pro modules. In general radio transmission from one to the other module is working correctly. But what I would like to do now is to send some test data across the radio link to the receiving Xbee and then in a loop back to the first module. The first (transmitting) UartSBee is connected via USB to my PC. At the receiving UartSBee I have connected TX and RX of the 6pin UART together.
This receiving module gets 3.3V power at the 3v3 pin of the UART, or alternatively via a USB connection. When I send data from my PC, the LEDs on both modules are flashing, but the data is not looped back to the first module.
So I am not sure, whether this configuration can work at all?
BTW, if I feed a single UartSBee (without Xbee) with data across a connected USB cable, the TX/RX loop is working correctly.
Thanks in advance for help.
