Issue LoadProhibited to TTN with LILYGO LORA32 1.6.1

hi all,
(sry if my english is not correct, i’m not englishmen)

I’have an and i try send/receive datas on service TTN with ide Arduino 2.0 with file example from Librarie de Thethingnetwork.

1 - I’have install esp32 + Oled + librarie TTNET
2 - Use example of librarie TTNET, here sendOTAA.ino with modification , i’m europe/France and i success in upload but i have issue next :

Guru Meditation Error: Core 1 panic’ed (LoadProhibited). Exception was unhandled.

Thanks for help.

My code in below:

TheThingsNetwork library is ONLY for The Things Uno board.

Try LMIC-node which is known to work with the TTGO boards.

Ah OK , i I’ll try.
Thanks Nick McCloud,
