Library to look up country codes (MCC) and carrier names (MCC-MNC) from Particle device firmware.
This library uses a table stored in code flash space and uses about 30K of flash space (out of 128K) so it's probably more appropriate for debugging tools.
The two functions implemented are:
String lookupCountry(uint16_t mcc);
String lookupMccMnc(uint16_t mcc, uint16_t mnc);
The tool works by taking the mccmnc.json file that's generated by the TowerInfo Tool and packing the data into significantly smaller C structures. The tool is in generator-tool and is run by doing:
cd generator-tool
node app.js
This generates the Carriers.h file from mccmnc.json.
