LoRa.begin() failed

[1n9yun]

Hello guys.
First of all, please understand that i'm poor at english. because i don't live in english-speaking countries.

Problem :
i'm using two "mkr wan 1300" for trying peer to peer communication.
so i installed this libraury. ( for LoRaReceiver, LoRaSender Example )

but i couldn't get the result i wanted.
only get the message : Starting LoRa failed!

What i did to solve :

• FW Update (1.1.9) with MKRWANFWUpdate_standalone example. also run serial monitor.
  ...

Suspected :
readRegister method in LoRa.begin( ) always return 0, not 0x12.

• maybe is it hardware problem?

and i heard the USB disconnect sound while uploading the source code.
but the upload is completed with no failure and the connection sound is heard again.

• is it normal?

i only had a USB connection with my laptop. i did not configure the circuit at all.

• do i have to configure it? if yes, please give me some example...

Thanks

I have the same problem using two mkr wan 1300 with the latest firmware, even after returning to the previous firmware version, I get the same error. The funny thing is it worked with the previous version of the firmware.

I'm sorry but I couldn't understand what you said..
Do you mean you solved the problem with previous version of the firmware??
then, which version you installed?

I flashed all the version.. but failed....................

No I didn't manage to solve the problem. It worked before with the previous version of the firmware, but even if I flash again with the same version, it doesn't work anymore.

Hi!
I have two MKRWAN1300 boards with the same issue. I have tried with FW 1.16 and FW 1.19 and Library version 0.5.0 without success.
