I am having a communication intermittency problem.
I have a node with Heltec Esp32 Lora 915MHz, Gateway: Dragino LG01-P and the TTN.
It works well, but often they randomly stop and no longer communicate until the Dragino is restarted. Sometimes not even with restart with you. I thought about putting a function to store the data in Heltec and send it after reconnection so as not to lose the information.
I realized that on hotter days the falls are constant. Even at almost the same time of day: from 1 pm to 6 pm.
Does anyone face similar problems? Any indication of Gateway to replace the LG01-P? Any solution?
