I have a custom PCB design for a production product, which I flash and programme using a Raspberry Pi prior to dispatch to customers. We have two identical boards, one with WROVER-B and the other with WROVER-IE. Both encrypt and then flash absolutely fine, but I'm finding that although the WROVER-B ...

I’m trying to do the same using an ESP32-Wrover. I’m not even able to set a GPIO pin gig during the wake stub.

Hi,

I need to run a timer to call a function whilst my device is in auto-light sleep. Is there a way I can do this using the RTC clock, so that the timer doesn't get disrupted by the sleep cycle?

Hi, When waking from deep sleep via a timer, I want to increment a counter and then go back to sleep. However, I also want to set wake interrupts for both EXT0 and EXT1 in the wake stub. I can do this no problem in the main code using esp_sleep_enable_ext0_wakeup and esp_sleep_enable_ext1_wakeup. Is...

I'd be very interested to know whether you ever got to the bottom of this, as I'm trying to do something very similar. My ESP32 goes into deep sleep, with EXT0, and EXT1 and Timer set as wake sources. When it wakes from timer, I need the wake stub to put it back to sleep with the same sources still ...

Hi, Is there a way to enable RWDT and continue to feed it during deep sleep, so that the device will do a full hard reset (incl. RTC) in the event it fails to wake from deep sleep after a pre-defined period of time (e.g. 1 hour)? Any code samples to point me in the right direction would be much appr...

I have a very strange situation on a number of production devices: all ESP32-wrover with SPIRAM enabled, running the same IDF version 3.3-r5, powered via battery and using the ESP-IDF Deep Sleep. Periodically, a device will wake up from sleep mode (usually following a timer expiry), but load into bo...

Hi, I've got a few devices which occasionally wake up from a deep sleep timer into firmware update mode, then because they are running on battery, get stuck until power is manually removed. We have nothing connected to GPIO0 when this happens (although the pin is exposed to a connector). Before goin...

I've identified that setting `CONFIG_CONSOLE_UART_NONE` in my config solves the reboot problem, but obviously prevents me from being able to turn on debugging when a 'normal' cable is connected. Is there any way in the ESP-IDF I can set the equivalent of `CONFIG_CONSOLE_UART_NONE` after the device h...

Hi, I have a situation where the power adapter I'm using (usb) results in the UART0 Tx and Rx pins being shorted - and as a result my device is failing to boot correctly. Is there a way that I can forcibly disable the Tx Rx on UART0 on boot so that I can avoid this problem? I could set them as I/O p...
