Re: Using printf inside Task

Maybe it's hanging in your NVS calls at the end.

Re: Network penetration on ESP32

I think you would have to perform that on your product. Security is based on your specific implementation of the security features available to you in the platform. You can produce a product with the ESP32 that has no security if you want.

Re: mqtt:fatal error: mqtt_client.h: No such file or directory

I'm guessing it should be right here.. C:/msys32/home/Administrator/esp/esp-idf/components/mqtt/esp-mqtt/include But I'm wondering why the IDF path to the project.mk is different than the one it's looking for that file.

Re: 2d Array and pointers

I'm doing this off the top of my head, but it should work..
typedef int arr2d[2];

arr2d myvar[] = {{11,12},{21,22},{31,32},{41,42},{51,52}};

or...

arr2d *myvar = {{11,12},{21,22},{31,32},{41,42},{51,52}};


void show (myvar *b,int l,int p);

Restart ESP32 with some timer mechanism of 5 seconds or 10 seconds
What's the point of the delay before reboot? I've been doing OTA without a delay before reboot and not sure if there is a potential problem.

Hi John, Just to check all the variables: how is 2.4GHz WiFi performance for other devices in the same environment? ie if you connect a PC to the 2.4GHz network (ie same router, same frequency ban...
