Apologies for people who probably understand all this better than me, coming from a GUI background from the ESP8266 - none of this was necessary ! Solution is if your running app_main then the file needs to be a .c file If you want to switch to Arduino you have to change the file to a .cpp file. And...

Also if I compile one of the esp-idf examples its fine, adding components and the arduino code it still compiles in both arduino mode and normal mode.

Its only when you remove the app_main and replace with setup and loop it just can not find it.....

Having installed everything as per the instructions. Ran make menuconfig to switch to Arduino style. Modifying a current example to run in Arduino style I am getting the error that undefined reference to `setup()' undefined reference to `loop()' I have files with setup and loop in them as per the in...

Cant believe I missed that, what a muppet , need to update esp-idf:)

Thanks !

Hi This is the last thing I need to get my project moved from the esp8266 where I use SPIFFS to save data. Is there anyway to replicate this yet, or another way to save a few KB of data on the esp32 easily - I have looked into the LUA port of SPIFFs, but not a good enough coder to work it out. Any e...

Do you have some example code for this - just attempting the same myself , help would be useful !

Thanks

Thanks so much !!

Thank you for the help - do you know of any example code doing this to have a look at ?

Regards

Is there any simple BLE examples for just sending characters across BLE ?

Thanks

Phil.

Thanks, sorted that now
