Closed selvamaniraj closed 7 years ago

selvamaniraj commented 7 years ago

Hello Sandeep, I am using ATSMAD21G18A with doorji lora sx1278. I have tried using your program that you uploaded in your github repository. I am getting an error "starting lora failed error". I am setting the frequency of 433E6 as you insisted in this link "https://github.com/sandeepmistry/arduino-LoRa/blob/master/API.md" but i am getting error. Can you help me with this issue. I have attached my source code with the screenshots and thanks in advance. screenshot 15 lora433mhz.txt

Hi @selvamaniraj,

Could you please share a photo of your wiring?

christopherdro commented 7 years ago

I've come across this a few times as well.

If the wiring is correct, try restarting the board. This has worked for me in the past.
