Re: OTA failure

Hey Sprite, Apologies I can't make the code public. But I can tell you that I now know that it occurs as a result of a disconnection coming mid way through a transaction over BLE with the Application we're interfacing with. We are not manually calling for a disconnect, but we are getting a disconnec...

Re: OTA failure

After some more digging I believe it may be something to do with the bootloader? I'll continue digging see if I come up with something

Semaphores and light sleep

Do semaphores need to be recreated after entering light sleep? I'm having issues where I'm unable to take semaphores after waking from light sleep.

Incorrect GPIO readings

Hey everyone, I've been trying to work specifically with a few pins connected to my battery, specifically 32,36,39 and 35. I know that I can only set 34-39 as input only, but I am trying to set 32 as high and for whatever reason when using gpio_get_level I'm not getting back the correct value. I'm r...
