Hi all,
please help me with connecting three rfd868ux modems with one for air vehicle and two GCS.as i have planned a mission from point a(gcs1) to point b(gcs2).over a range of 15km
I have configured all 3 radios as mentioned below. i am sure that all radios are connected with each other since all the radios have solid green light and through AT and Rt commands.

also changed GCS ID of both GCS as 254,253
the problem here is mission planner not able to connect with air unit i.e when one gcs is connecting other gcs is not connecting to air unit and vise versa.
please suggest me how to establish communication of both GCS with air unit simultaneously without any lag and interference to telemetry data.
Hello yashika,
Can you tell us the value of:
AT&M
Thank you.

Hello,
OK. Yes that is what I would configure.
Have you made any progress?
I bought some RF 868x in a few days, I hope they arrive.
I inform you of our configuration.
We want a ground station and two air vehicles.
Regards.
After many unsuccessful attempts we got to know that due to the limited number of channels available on the 868 MHz band this firmware may not
operate as intended and is not recommended for 868X modems or reduced band settings less than
915-928MHz on 900X modems
