I want to send RTCM correction messages from the Sparkfun F9P base to F9P rover via Xbee. I have RTK fixed mode on my rover F9P using a wired connection, so I know the two F9P's are correctly configured per Ublox's Moving Base Application Note. I now want to replace the wired connection with a wireless connection between the bas and rover GPS's.
Following Sparkfun's advice, I configured my two Xbee 3 firmware to the legacy 802.15.4 protocol. My two Xbee 3 modules are talking to each other via Sparkfun Explorer adaptors when I type in XTCU console log. I set the Xbee 3 baud rate as the F9P's, namely 115200. Other than change the PAN ID, I made no other changes to the XBee 3 default settings.
My multimeter indicates about 3.3V at the F9P UART2 TX pin which outputs the RTCM messages. However when I connect this output to the Xbee 3 DIN pin, there is no data appearing on the XCTU console log. Could you please help me set up this wireless link between the pair of F9P receivers.
