Seems likely that #3517 also applies to all ESP32 devices, not just Heltec Wireless Paper. |

I can confirm that the program button on Heltec V3 now wakes the device from PowerSave mode as it used to. Thank you. I believe you fixed it. |

Hopefully addresses #3512
Main culprit seems to have been the addition of
enableLoRaInterrupt(), which is competing with the hardware button for use of the EXT0 wake source. Using GPIO wake for the button works around this issue.Secondary issues with ISRs on wake, and PRESS event detection have also been addressed (kludged).
Tested with Heltec Wireless Paper, however this does currently require a hotfix for #3517 to first be applied. Will be separately address soon. Briefly tested with T-Echo. All seems to be running fine, at least at first glance.
I would expect this bug to affect all ESP32 devices(?). It would be good to have the fix independently tested, if anyone has the time / energy to spare.
