i mean a GW LoRa with two corecell sx1302/03 concentrator boards configured with the same channel plan,
As a single SX1301/2/3 supports 8 channels (multi-SF), this would give you still 8 channels instead of 16.
I would suggest:
- SX1302/3 1 - Packet-forwarder configured with channels 0 - 7
- SX1302/3 2 - Packet-forwarder configured with channels 8-15
Then you could use a single ChirpStack Gateway Bridge. Add two gateways to ChirpStack and configure ChirpStack with 16 channels.
