M2 as base and reach RS3 as rover

Reach Module / M+ / M2 RTK / PPK configuration
1

Dear all,

I am trying to connect M2 as base with RS3 as rover through LoRA. I check all the settings and I think they are right. The M2 LoRA module is correctly connected and switches on when I power M2 but TX RX led do not switch on and RS3 rover does not receive corrections. All the firmwares are updated. Could it be a problem of compatibility?

THanks a lot and regards
Stefano
