Error when compiling DeviceInfo example for ESP8266 board #269

Open vonsivers opened 3 years ago

Hi there, when trying to compile the DeviceInfo example for Board "Generic ESP8266 module" I get the following error.

Arduino: 1.8.13 (Windows Store 1.8.42.0) (Windows 10), Board: "Generic ESP8266 Module, 80 MHz, Flash, Legacy (new can return nullptr), All SSL ciphers (most compatible), no dtr (aka ck), 26 MHz, 40MHz, DOUT (compatible), 4MB (FS:3MB OTA:~512KB), 2, nonos-sdk 2.2.1+100 (190703), v2 Lower Memory, Disabled, None, Only Sketch, 115200"

C:\Users\Moritz\Documents\Arduino\libraries\TheThingsNetwork\src\TheThingsNetwork.cpp: In member function 'ttn_response_t TheThingsNetwork::poll(port_t, bool)':

C:\Users\Moritz\Documents\Arduino\libraries\TheThingsNetwork\src\TheThingsNetwork.cpp:652:41: error: 'class Stream' has no member named 'getTimeout'

   long timeout = this->modemStream->getTimeout();

So it seems like the ESP8266 Arduino libraries are not complete and do not implement the getTimeout() function. A proper fix would be to add this function to the ESP libraries. A workaround could be to "guess" the value and just assume we are close enough. Normally a timeout would be in the order of 1 second.

So I changed the following line in TheThingsNetwork.cpp 

//long timeout = this->modemStream->getTimeout();
long timeout = 1000; in your library to

I can compile the code now, however, after upload the MCU crashes with the following exception

At this point maybe try a tool like https://github.com/me-no-dev/EspExceptionDecoder/tree/1.1.0 to decode the above crash into a more usable format. Hopefully that will indicate on which line the program is crashing.
