  • When I try the simple example "MG2639_GetInfo" I get this warning during building "WARNING: Category '' in library SparkFun MG2639 CellShield is not valid. Setting to 'Uncategorized'"

    Then, when I upload the sketch and start the program by sending some chars on the serial line, the MG2639 RSSI led blink quickly during 2-3 sec then stay OFF and I get the following message "Unable to communicate with shield. Looping".

    Im using using the last Arduino IDE version, with a RedBoard, external 9V power, standard SMA antenna for the GSM. Exactly like in the hookup guide.

    Does anyone have an idea?

No public wish lists :(
