Prerequisites
Monogoto SIM
Quick Navigation
Set up EVB Kit (if applicable)
Set up the EVB Kit
Connect the Quectel BG95-S5 modem to the EVB kit.
Connect the LTE antenna and GPS antenna
Insert the Monogoto SIM
Connect your PC to the EVB Kit
Use the USB to UART converter cable to connect your computer to the COM1 MAIN port of the EVB Kit
When using Windows, install the driver using the disk or USB stick provided by Quectel.
Connect to the EVB kit using a terminal program. You can use PuTTY for Windows, or screen, minicom, or miniterm for Mac or Linux.
Power the EVB Kit using the USB to micro USB cable and switch the POWER button to ON. The POWER LED will turn on RED.
Press and hold the PWRKEY button for 1 second, the STATUS light will light up on GREEN, the NET_STA LED will start blinking BLUE.
Once the modem has started, it will report:
Enter AT, if the connection with the BG95 modem has been established, the board will answer with OK.
Connect the BG95 to Monogoto
Keep the AT Commands manual next to you for more details about the commands. Click here to download the latest version.
Reset the modem to its default configuration:
Reset non-volatile memory:
Restore factory settings:
Reboot module:
Set the error reporting to verbose, resulting in more descriptive error messages (optional):
Check the status of the SIM card. The correct response should be: +CPIN: READY
If you receive an error, the SIM may not be inserted properly or the SIM is protected with a PIN. By default, Monogoto SIMs are not PIN protected.
Query device information
Request the product type, hardware and firmware version:
Example response: AT+QGMR BG95S5LAR08A01_A0.203.A0.203
Request the IMSI (International Mobile Subscriber Identity):
Request the ICCID (Integrated Circuit Card ID), which is the identification number of the SIM card
Network Configuration
It is possible to let the modem select the network automatically.
Automatic Network Selection
To set the modem to automatic network selection enter the command:
Configure Radio Access Technology (RAT)
Configure the modem to only use NB-IoT NTN not LTE Cat-M1:
Set the APN to data.mono:
Lock the modem to a specific region/band
Although the modem may support many different NTN bands,
0x1 = 23 United States region
0x2 = 255 L band Global (Taiwan, Australia, New Zealand, Japan)
0x4 = 256 S band Europe
Query Network information
To information about the technology used, the network provider and cellular band, enter:
Example response: +QNWINFO:"NTN NBIoT","90198","NTN NBIoT BAND 23",229155
Reports the information of serving cells
Example response:
+QENG: "servingcell","LIMSRV","NTN NBIoT","FDD",901,98,2DCEAE,30,7699,23,0,0,7EE,-120,-13,-115,85,
Check the radio signal strength and signal quality:
+CSQ returns 2 values separated by a comma. The first value represents the signal strength and provides a value between 0 and 31; higher numbers indicate better signal strength. The second value represents the signal quality indicated by a value between 0 and 7. If AT+CSQ returns 99,99, the signal is undetectable or unknown.
Check the current network registration status
response:
Validate if your device received an IP address:
Expected response: +CGPADDR: 1,XX.XXX.XX.XXX
Do you see an IP address? Congratulations! You’ve successfully connected the Quectel modem to Monogoto 🎉
Test the connection by sending a PING
A PING test can be performed to test if the modem has an active data connection with a mobile network.
When cellular modems are idle for a long period of time, cell towers might drop the data connection to save resources. Sending regular PINGs is a good method for testing the data connection, as well as for keeping the connection alive because the operator registers your device as being actively used.
Send 3 PINGs to IP address 8.8.8.8:
