<![CDATA[UWB module not communicating through UART]]>Hello,
I purchased the UWB module (DW1000) and I currently have the device connected to a USB to UART bridge (CP2102). I cant seem to be able to send AT commands through the UART.
I made sure device is communicating by disconnecting the device and connecting it back to the UART bride. I use putty (buad rate 115200 per documentation) and see that there is chatter. I have also tried to switch the RX and TX lines. I have also verified that my USB UART bride is outputting 5V.

The documentation says if you input the command "AT" it should return a message "OK", but I do not see that. If you have any advice on why this module is not working I would appreciate it!
