Bridges NOTE All other interfaces and test points, which are not mentioned in the table above, are reserved for debugging purpose only - they are not for customers.
- Page 13 LPWA Module Series Application Interfaces 3.1. UART Interfaces Figure 3: UART Interfaces UART_CLI is for firmware upgrading, software debugging, log outputting and GNSS data and NMEA sentences outputting. UART_DBG is used for RF calibration and log outputting. UART_GNSS is for GNSS firmware upgrading, GNSS data and NMEA sentences outputting.
- Page 14 LPWA Module Series Figure 4: CP2102N Driver Installation 3.2. BTB Connectors The BTB connectors are used to connect TE-A to UMTS<E EVB. Most module pins are connected to BTB1 connector; some pins are connected directly to TE-A’s peripheral circuit or test points; and no pins are connected to BTB2 connector.

- Page 20 LPWA Module Series Operation Procedures 4.1. Physical Assembly The connection between BG950A-GL/BG951A-GL TE-A, UMTS<E EVB and main/GNSS antenna is presented below: Figure 7: Connection Between TE-A, EVB and Antennas 4.2. Turning On/Off Module The turn-on/off procedures of BG950A-GL/BG951A-GL TE-A are controlled by TE-A itself and UMTS<E EVB.
- Page 21 LPWA Module Series NOTE 1. With the TE-A and UMTS<E EVB, BG950A-GL/BG951A-GL support automatic power-on according to the steps illustrated below: a) Connect the TE-A to the EVB. b) Power on the EVB by connecting it to a power supply and switch S201 (Power Switch) on EVB to “ON”...
- Page 22 LPWA Module Series NOTE The CLI UART of BG950A-GL and BG951A-GL is directly connected to TE-A's CP2102N by default. Therefore, COM2 of UMTS<E EVB cannot be used for debugging. 4.4. Firmware Upgrading If the module can be turned on normally, you can directly upgrade the firmware through UART_CLI on the TE-A.
- Page 23 LPWA Module Series GNSS Procedures For the BG950A-GL module, GNSS and LTE are time-division multiplexed and no independent GNSS chip is used. For the BG951A-GL module, GNSS and LTE functions are concurrent and an independent GNSS chip is used. This chapter introduces the GNSS operations of BG951A-GL as reference. 5.1.
- Page 24 LPWA Module Series 5.2. GNSS Firmware Upgrading If you need to download or upgrade the GNSS firmware, follow the steps below: Insert the Micro-USB cable of UART_GNSS. Switch the GNSS_BOOT switch to “HIGH” state so that the GNSS chip enters emergency download mode.
