what type of gateway are you using… single channel ?

its a pi supply lora gateway with ic 880 and raspberry pi 3B+ . I am not sure about channel

did you just build it ? did it worked before ?

i got it from someone. bt it was working at his place

it is multi-SF channel

“Normal” behavior with standard spi speed. Try to reduce the spi clock to have it connect 100% of the time, or just wait and the board will try to connect again, after 2-3 tries it usually works (and stays connected till the next reset).

Make sure the reset pin being driven is the one actually connected to the concentrator.

can you just elaborate what you want to say? i am not understood you exactly.

Yes. the RESET pin is work properly.
