http server simple example not working (v4.2)
Hi everyone, I'm trying to run the http server simple example but it doesn't seem to work.
Considering the message from the serial port it seems that there is some problem with registration of the uri handler.
Thank you for your valuable advice.

Merging two esp idf examples
Hi guys, I'm trying to merge two esp-idf example, "Modbus master" and "http_server" (using visual studio and visual gdb as debugger).

Re: master esp idf 4.2 Characteristic read fail error
Hi ESP_alisitsyn, yesterday I solved the problem by changing the type of data in the CID description (from float to uint8).
I'm not completely sure that this was the source of the problem, however now it seems to work (it store the temperature value in the "value")
