Re: Changing partition size via OTA

if I could access additional memory via an OTA software update, that would be really useful What exactly do you want to do with it? That determines how difficult it is to do so safely. Particularly, if the bootloader needs to be aware of the change (eg. you want to move/add/resize app partitions) t...

Re: soc version needed for analog read linearisation

Code: Select all

#include "sdkconfig.h"
It's almost certainly already indirectly defined as many other headers will be including sdkconfig.h.

Maybe .end()? Maybe not. I was only guessing sorry.

 I'm not sure why scan results would be cleared by a handler
Not explicitly, but esp_wifi_scan_get_ap_records frees the records internally, ie. it can only be used once per SCAN_DONE.

Re: IP_EVENT_AP_STAIPASSIGNED is never called in AP-Mode

You have registered a handler for WIFI_EVENTs, but not for IP_EVENTs.

Re: Mixing WiFi.begin() and esp_wifi_scan_start - help needed

It looks like the Arduino WiFi event handlers are still registered in the latter case, so the scan results are fetched (and cleared) in the SCAN_DONE event before you have a chance to grab them. Maybe WiFi.stop() will do the trick for this problem, but you can probably expect more issues to appear w...

Re: Having major problems with my own handlers for my libraries

Possibly due to sensor_internal_i2c being a stack variable. Do you delete app_main's task, or does sensor_internal_i2c go out of scope?

Re: Core 0 is Slower

The main task (the one that calls setup and loop) is pinned to core 0 in Arduino. Your loop is while(1); so this will occupy quite a lot of core 0's time. Delete or suspend the task instead. There are FreeRTOS utilities to help debug issues like this: https://www.freertos.org/a00021.html#vTaskGetRun...
