Arduino + ESP8266 - Problems using Modem from Contrib

[rafaelb4rreto]

Hello!

As discussed in post #297 , the files from contrib/src/modem seems to have wrong #includes.
So I put all the files from /contrib/src/modem and from /contrib/src/modem/db and the contrib/src/SerialTransceiver.h renamed to "SerialTransceiver2.h" in the same dir of the sketch and changed the #includes untill the code from the sketch get sucessfully compiled.
The sketch is a copy of the example in /contrib/examples/FirebaseSerialTerminal_ESP8266/FirebaseSerialTerminal_ESP8266.ino (for test the protocol from the terminal). The only modification in the .ino was "#include <SerialTranceiver.h>" to "#include "SerialTranceiver2.h""

Opening the terminal, the ESP8266 send "Connected: 192.168.bla.bla". Ok!
Then I put the command "BEGIN_DB <my_host> <my_secret>" and the board send "+OK". Cool!

But when I put "SET blabla" or "NETWORK" or "SET: blabla" it returns "-FAIL Invalid command 'SET'.
", for exemple.
AND the most strange is that the board understand the command "GET", but it always returns something like: "GET /blabla.json: connection refused".

Has anyone got this working? Does someone know what is happening? Thanks!

We would appreciate if you can help us fix and make modification to contrib/modem as recent changes were not tested on real hardware. Feel free to fork and suggest pull requests.

Ok! I will suggest a pull when I fix it.

I fixed this bug: But when I put "SET blabla" or "NETWORK" or "SET: blabla" it returns "-FAIL Invalid command 'SET'.", for exemple.

Basically the binary_search() in firebase-arduino/contrib/src/modem/SerialTransceiver.cpp, line 28, was not working.

But now all the others commands return "-FAIL GET /blabla.json: connection refused", for exemple.

I dont know what to do anymore.

Using the FirebaseDemo_ESP8266 example I had the same output of the #357 and it never get connected:
