Heltec ESP 32 WiFi LoRA v3 deep sleep on LoRA

Postby cferry » Fri Jul 12, 2024 7:21 pm

Hello,
I have the Heltec ESP32 v3 board and i am using the Heltec unofficial library.
Its a good dev board so far but I have started to mess around with sleep modes.
I would like to put the board into deep sleep and wake when a message comes in through the LoRA chip.
However, this never really works, I see that my device resets all the time and i have used GPIO14 as the IRQ as it shows in the schematic that DIO1 is connected to GPIO14.
I have sanity checked and can get the board to wake up using the PRG button on GPIO0.
I was wondering if anyone else has come across this or if there is something i am missing.
Thanks

Good Morning,

Working on a similar project using the Ebyte E220-900T30D; wake on radio and ESP32 deep Sleep. Project is unfinished; have issue sending message. Believe smoke is out of one of transceiver modules. Awaiting replacement. Ebyte E220 requires a RTC pin be used on the AUX pin; your device may be the same for the extenal deep sleep wake up.
