Hi mfalkvidd,

thanks for the welcome :upside_down_face:

You're right, I should use RFM95 and I changed it. However the same error:

208 MCO:BGN:INIT NODE,CP=RLNNA---,FQ=8,REL=255,VER=2.3.2
335 TSM:INIT
350 TSF:WUR:MS=0
378 !TSM:INIT:TSP FAIL
401 TSM:FAIL:CNT=1
421 TSM:FAIL:DIS
440 TSF:TDI:TSL

Also I tried the log parser earlier but it just tells me "Transport device initialization failed". I need to figure out why it can't initialize that device. I quadrouple-checked the wires and can't see any issues :unamused:

However here are some pcitures of it, maybe you find an issue? (Sorry, wiring is a bit messy :alien: )

@mfalkvidd I tested shorts with my multimeter and didn't find any shorts. However I should receive next week some new of these chips and I will try to solder them new. Let's hope that that's the issue!

FINALLY!

My replacement arrived and I soldered it to my pro mini. This time I used a level converter for powering it directly from VCC and not the arduino's VCC. First no luck, but after switching MISO and MOSI it finally worked:

Seems like the diagram of the shop where I bought the arduino is switched. However I can now try to read the sensor and send the data via LoRa! Awesome!

One final question (not related to this issue but maybe you can still answer that in this topic :innocent: ) : I got a RXB6 runnign to read a radio rain sensor at 433MHz. Is this received able to recive also LoRa signals or do I need a dedicated LoRa chip to receive LoRa radio signals?
