Re: I disabled watchdogs but I still get a WDT timeout
You disabled wdt on looper task only, not that new task. Another thing is why not use peripheral to do it, like ledc, spi or rmt?

Re: BLE Security Passcode
Example with static pin is very simple and it works. All you have to do is to add 2 lines to your code: BLESecurity *pSecurity = new BLESecurity(); pSecurity->setStaticPIN(123456); https://github.com/nkolban/esp32-snippets/blob/master/cpp_utils/tests/BLETests/Arduino/security/StaticPIN/StaticPIN.ino

Re: ESP32 or ESP32-2 or ESP8266 supports external MCU
It was just example, how esp32 is used with other MCU as wifi. In maixduino the MCU is kendryte k210, esp32 is controlled over SPI and is using NINA modified firmware (in addition 6 ADC is exposed over SPI). Second link is NINA firmware that is designed for u-blox series but can be installed on any ...

Re: Building project with libnmea-esp32 component
First thing you should do is to move libnmea 1 folder up in tree, because you dont have CMakeLists.txt in libnmea-esp32. Then probably add to your CMakeLists.txt in main:

Re: Make causes antimalware executable to run at high cpu and memory
Just a suggestion, if you have older PC with old hard drives, then dont use make -j, try with make -j 6 or something to match you core number. With NVM PCIE it may work, because this drive is capable to do many I/O operations per sec, but older disk will slow down whole process.

Re: Cannot Find BLE Advertisement when scanning
There seems to be nothing wrong with those data, the question is rather about your code. How do you handle scan.
