RAK831 with 433 MHz frequency plan

[ferrero]

Hi,

For now, my configuration is

• A RAK831 433MHz version
• I just modify the global_config.json file according to Rak support recommandation and with my 433 frequency plan:
• I add it to TTN with EU868 or US915 freq plan (as EU433 is not available)

  -I’m using a custom board with RFM95W and Arduino Mini Pro.

Uplink is working perfectly (so ABP works fine), but downlink is done at the wrong frequency (depending on the freq plan selected).

As an exemple, here is what I have to OTAA and US915 freq plan.
