I’m currently trying to use a pair of Microhard P900-ENC (http://www.microhardcorp.com/P900-ENC.php) to serve as the Telemetry radios for the HolyBro Pixhawk 4. Because the radios use an RS232 connector, I’ve also acquired a TTL to Serial convertor (https://www.maximintegrated.com/en/products/interface/transceivers/MAX3232PMB1.html).
While both radios have been configured correctly to talk to each other, I can’t seem to get any information to be transmitted over the radios from the Pixhawk to the ground computer. I’m not too knowledgeable about serial radios, so I was hoping some folks here could help provide some insight as to what I can do to try to troubleshoot it?
Thanks in advance for the help.
