HTTP testing with Simcom SIM7070, SIM7080 Modules
Steps to test HTTP GET with SIM7070, SIM7080 Modules
- Verify that the device is registered with the network provider
- Query the network using the AT+CGNAPN command
- Activate the network bearer using the AT+CNACT command and verify that the activated bearer profile has IP addressed using the AT+CNACT? command.
- Set up the HTTP parameters using the AT+SHCONF command
- Set up the HTTP head using the AT+SHAHEAD command
- For HTTP PUT requests, setup the URL parameters with the AT+SHPARA command
- For HTTP POST requests, setup the POST data with AT+SHBOD command
- Send the HTTP GET/PUT/POST request using the AT+SHREQ command
- Read the HTTP response using the AT+SHREAD command
