Modem FW Update
Each qTop BG9x LTE/GNSS AMC Shield contains Test Points to upgrade Modem FW.
To make FW upgrade these equipment setup steps to be done:
 These Test Points to be connected to Host (PC) USB interface:
o TP9 : USB_VBUS
o TP10 : USB_DP
o TP11 : USB_DN
o TP13 : GND
 SP1 PCB Jumper should be closed;
 After Device and Modem power on, Modem will be enumerated as serial
port;
 Follow Modem FW Upgrade steps, described in appropriate app note
document.
Test Points could be connected to the USB cable by soldering as at picture below
or by pogo pins (https://www.digikey.com/en/products/detail/mill-max-
manufacturing-corp/0914-0-15-20-77-14-11-0/1147053 ).
As soon as FW upgrade finished, SP1 PCB Jumper should be opened.
Getting Started
qTop BG9x LTE GNSS AMC Shields could be used with the most Arduino MKR IOT
boards (Main Board).
To get board up and running these steps to be done:
- LTE and GNSS antennas MUST be connected to PCB u.FL connectors (directly
or using u.FL-SMA adapter cables);
- SIM Card should be inserted;
- Appropriate FW should be flashed into Main Board;
- qTop Modem Shield should be plugged in right direction into appropriate
connectors of Main board;
- If needed, qJam device could be plugged into Shield qJam connector;
- LiPol Battery or +5VDC 2.0+A power supply should be connected to a Main
board.
