Any people with iTracker RAK8212 here?

My proposal for selecting between CREG or CEREG is pass a key named 'lte' in options{}. If this is true, use CEREG, else CREG

Hopefully I've used the correct javascript idiom for testing to see the key exists or default to false. If not, please correct me after you've stopped laughing.

In the connect function:

atcmd("ATE0").then(function() { // echo off
        if (options.lte || false)
        return atcmd("AT+CEREG?"); // Check LTE registered
        else
            return atcmd("AT+CREG?"); // Check GSM registered
    }).then
