Hello, I was trying to connect the MKR GSM 1400 to the hologram network but it seems that the device hangs when it reaches the line
if ((gsmAccess.begin() == GSM_READY) && (gprs.attachGPRS(GPRS_APN, GPRS_LOGIN, GPRS_PASSWORD) == GPRS_READY))
After some research I was made aware that this issue was fixed in the 1.31 version of the MKRGSM library. I'd like to know if the board is defective or if there is something I have not done correctly.
The board is using the provided antenna along with a working SIM card from hologram. The board when connected to the PC through USB is also connected to a 3.7V LiPo battery that is connected to the VIN and GND pins on the MKR1400. I have also tried the 5V and GND pins. The reason why I have not plugged in the LiPo battery directly into the connector is because it does not fit.
The sketch I was using is provided by Hologram at https://help.hologram.io/connection-instructions-for-3rd-party-hardware/development-boards/arduino-mkr-gsm-1400.
