ESP32 - GPIO39 Glitch with BLE Modem Sleep
Posted: Thu Jan 21, 2021 4:50 am
Hello Everyone,
I saw in the chinese forum someone report the same issue. There is an issue where the ESP32 will pull-down GPIO39 when modem sleep is enabled. This is not directly noted in the Errata. I suggest the team update the errata to show this.
I'm also wondering if there is anyways to prevent this triggering an interrupt? Is there anyway I can be given a handle/hook to disable / re-enable interrupts during this mystery pull-down event? I'm looking for a solution to prevent a board spin.
