By default, upon boot the GPy will create a WiFi access point with the SSID gpy-wlan-XXXX, where XXXX is a random 4-digit number, and the password www.pycom.io.
The RF switch that selects between the on-board and external antenna is connected to P12, for this reason using P12 should be avoided unless WiFi is disabled in your application.
Power
The Vin pin on the GPy can be supplied with a voltage ranging from 3.5v to 5.5v. The 3.3v pin on the other hand is output only, and must not be used to feed power into the GPy, otherwise the on-board regulator will be damaged.
AT Commands
The AT commands for the Sequans Monarch modem on the GPy are available in a PDF file.
Tutorials on how to the GPy module can be found in the examples section of this documentation. The following tutorials might be of specific interest for the GPy:
