Assemble the SIM7000A development kit
Connect the SIM7000A-TE board to the SIMCOM-EVB board as shown in picture below.
Install the drivers
- Download the CP210x USB to UART bridge Virtual COM Port (VCP) driver from the below link,
Connect the USB port on the SIMCOM-EVB board to USB port of your computer. If the VCP drivers are installed successfully, 2 virtual COM ports should be visible under the PORTS in Device Manager.
Connect the SIM7000A board to AT Command Tester
After the drivers are installed, launch the AT Command Tester application. Connect to the enhanced COM port (COM4 in above case). Please note that the standard and enhanced ports may enumerate to different port numbers in your computer.
Run diagnostics commands with SIM7000A module
Using the tool, run diagnostics AT commands on SIM7500A module.
Check Network Connectivity on the SIM7000A Module
Get the signal strength and the registration status on the SIM7000A module. If the module is unable to acquire the signal, registration will not be possible. Check the antenna connector on the board. Also verify the band is properly configured on the SIM7000A module.
Set up Packet Data Protocol (PDP) profiles
Set up APN in the PDP profile. Check with the network provider regarding what APN should be provisioned for your network.
Setup TCP/IP connection with SIM7000A
Using the AT Command Tester tool, setup TCP/IP connection with the SIM7000A module.
Test HTTP feature with SIM7500A module
Use the AT Command Tester tool to test HTTP GET and POST features of the SIM7500A module.
