Adafruit Fona library for Arduino Uno Wifi Rev2

[mahmoodalam]

Hi,

I have the "Adafruit FONA 808 Shield - Mini Cellular GSM + GPS for Arduino". I want to use this shield on Arduino Uno Wifi Rev2. Where can I find the supporting fona library ?

Thanks.

The Adafruit Fona library mentioned by you is working for the Arduino Uno and not Arduino Uno Wifi Rev2. With the later it is giving compilation errors, shown in the file attached. Can you help me in identifying the errors and fixing them.

Oh lovely.. the Arduino board support package disabled the F() macro, which broke all the relevant type declarations in the FONA library.

You should be able to work around most of the trouble by changing this line of FONAPlatStd.h

https://github.com/adafruit/Adafruit_FO ... tStd.h#L59

to this:

Code: Select all

typedef const char *	FONAFlashStringPtr;

And then you'll have to change this part of the header:

https://github.com/adafruit/Adafruit_FO ... #L202-L207

to convert all the string storage to type 'const char*':

Code: Select all

  const char apn[ 4 ];

for instance.
