Light Sleep issues with BTLE & High deep sleep power
Posted: Thu Nov 22, 2018 3:50 am
Hi,
Two part issue that may be linked together.
I'm running into assert fails when waking from light sleep, and very high current draw when in deep sleep.
These are most likely related, and so figured i'll mention them together.
When I put the ESP32 into light sleep (using timer for wakeup after approx 10 mins), everything wakes up and runs fine until I try and enable the bluetooth again.
I'm using a helper function for BT control (at end) and this works fine without sleep modes being used in the code. However whenever i have the sleep I run into whenever i try and re-enable the BT after waking up.
The second issue is that entering deep sleep mode appears to work, but it has a very high power consumption (18mA), where as light sleep uses only 2.5mA.
I believe I have the correct sequence for shutting down into deep sleep, but apparently this is not the cause. Would love any help
For the BT, is this a known issue of some kind or am I doing a step in the wrong order ?
ESP Module is the WROVER with the 4MB PSRAM
