I must be dense because I cannot figure out how to get my new LoRa Serial kit to work in multipoint mode.

I have switched both units to AT-OperatingMode=0. I have set the same AT-Bandwidth on both. I have set AT-Server=1 on one and AT-Server=0 on the other.

I then ran ATT on both and saw:

```auto
Server training parameters
  Training netID: 192
  Training key: 537061726B46756E547261696E696E67
Server radio protocol parameters
  netID: 192
  Encryption key: 37782141A665734E4475672AE6308308
OK
Client C208853D5730305020312E50212A09FF Trained

```

and

```auto
Link trained from D9EFD0575730305020312E50221E09FF

```

I exited command mode on the server and it just shows all 4 RSSI lights lit.

The “client” shows no RSSI lights lit and I don’t seem to be able to send information between them with the serial console.

I tried several reboots.

I must be missing something, but not sure what.

Oops, I posted this on Miscellaneous based on where another Lora post was. I guess it should go in Wireless or Kits.
