SIM and APN setting
1. Install SIM of cell phone to GPRS module.
2. Sent message to SIM number to read and write APN.
| Read APN information | |
| Sent | AT+WXAPN? |
| For example: Set 'AT+WXAPN?' to 86-13725501611 and get back message as following: AT+WXAPN? +WXAPN: CMNETI.gprs.com OK | |
| Write APN by message | |
| Sent | AT+WXAPN=APN name |
| For example: Sent ' AT+WXAPN=airtel.gprs.com' to 86-13725501611 and feed back message:AT+WXAPN=airtel.gprs.com | |
If the APN can't modify by message of GSM, please change APN by debug software in computer
1. Wire Rs485A , Rs485B to USB to serials port converter, and wires
24V , GND as well.
