Wifi lora 32 v2 reset after sometime

michelpaz · June 9, 2023, 8:16pm

Hi guys, I have a helteck wifi lora 32 v2 and Im trying to do a communication between 2 of them. The first one is only sending messages by Lora but the second is receveing messages by Lora and sending it by MQTT. I have some functions to reconnection and to check the connections between the devices. All works good, but after a while both devices reboot (not at the same time). How can I do? I'm going to paste my codes. I hope you can help me. Thank you.
