Support Generation of Gateway Configuration for 16/64 Channel UDP gateways #1837

Open MathieuMonneret opened 4 years ago

MathieuMonneret commented 4 years ago

Summary

Add support to return a UDP packet forwarder global_conf.json with multiple concentrator support. see also #761

Why do we need this?

This is to support the configuration of 16 (or more) ch gateways with UDP Ex: Cisco Wireless gateway and Kerlink.

What is already there? What do you see now?

pfconfig supports only SX1301_conf object.

What is missing? What do you want to see?

support also SX1301_array_conf object.
