Why assign a boolean to a string?

[trixymoon]

the instruction modem.setNetworkMode(2); at line

LilyGO-T-SIM7000G/examples/Arduino_TinyGSM/AllFunctions/AllFunctions.ino

Line 151 in c163bb7

res = modem.setNetworkMode(2);

return a boolean

Just do:

if (!modem.setNetworkMode(2)) {
        DBG("setNetworkMode  false ");
        return ;
}

and it's the same for the instruction modem.setPreferredMode(3); at line

LilyGO-T-SIM7000G/examples/Arduino_TinyGSM/AllFunctions/AllFunctions.ino

Line 163 in c163bb7

res = modem.setPreferredMode(3);

if (!modem.setPreferredMode(3)) {
        DBG("setPreferredMode  false ");
        return ;
}
