My Modules do not work #1

Open SensorsIot opened 5 years ago

Hi, I tried to get the modules running, but without success. How can I check if the wiring is correct? Maybe a small test-sketch which reads a known register? And How can I produce a signal I can see on my spectrum analyzer? I would like to create a video about these chips. Maybe you know my channel (Andreas Spiess)

Hi Andreas, I had the same problem using the Ebyte E282G4M12S modules coupled to 3.3.V 8MHz Pro-Mini boards - until I tried reversing the MISO/MOSI connections! As in: E282G4M12S MOSI_RX to Pro Mini Pin 11 (MISO) E282G4M12S MISO_TX to Pro Mini Pin 12 (MOSI)

Then everything works OK....

ADDENDUM: I was referring here to the pinout diagram for the RobotDyn board but looking around it seems to be a common mistake on several other pinout diagrams- quite a few have MISO/MOSI "reversed". Anyway something to try.

I highly recommend Stuart Robinsons Arduino SX1280 library- recently posted at https://github.com/LoRaTracker/SX1280. He has a connection test program here.

Would be very interested to see a video from you about all this- I really enjoy your videos (I am a subscriber!)
