I have been using the RNT lab Sketches for sending and receiving “hello World”.
The sending module prints to the serial monitor that packets are being sent.
The receiving module prints to the OLED ” LoRa receiver” then “LoRa Initializing OK” but nothing after that.
i added a line to print to the serial monitor the value of LoRa.parsePacket() is “0”.
I have tried several different boards in case one of them was fried, but the results are always the same.
I can’t determine if the packets really are not being sent, or not received for some reason.
Unsure how to troubleshoot from here. Any help appreciated.
What exact code/example are you trying to follow?
Also, can you send me a link to the LoRa board you’re using?
If you’ve modified one of our examples, remember that you need to call the display.display() function whenever you want to display new information on the OLED. If you don’t call display.display() the changes won’t take effect.
I’m sorry for taking so long to get back to you.
Thanks for taking the time to write back. Since my post, I have gone back to the very basics and loaded the LoRaSender and LoRaReceiver examples for the Heltec ESP 32 OLED boards. I was able to send “hello world” form the sender to the receiver so I know that the boards are still working.
I will slowly add the OLED read outs etc now knowing that I am not wasting my time with a non functional board.
Thanks again for your help…. hope that it is nice and sunny in Portugal 🙂
