RAK 7289v2 doesn't recconect

Hey everybody!

I’m developing a system that has 2 sensors with RAK4630 that have to measure a lot of parameters through BSEC library.
A few weeks from now, I successfully connected my gateway to a TTN server and in my first code I was using LoRaWAN and OTAA to pass my parameters to TTN. The problem in this was that I could only pass Temperature, Humidity and Gas Resistance.
Then I developed another code using BSEC library and if I connect the sensor to my PC, i can see the values of other data that i configured in my Serial Monitor, but never could pass those values to TTN.

The major problem was when at the company, they shutdown the power supply and my gateway disconnected from the server and now i can’t reconnect any longer.

So my questions are:
Is it possible to use BSEC library and input it in a payload and send it successfully to a TTN server?
How can I “rebuild” my gateway? I have already press reset more than one time and tried to link it in WisGate but all those attempts were unsucessfull.

Can you help me out?
King regards,
João
