How to use it ?

• 1.Please check the SIM card and DIP switch. The SIM card holder in the back of the A6,you can turn on the DIP Switch 1,3,5,6
• 2.Plug USB,turn on the power
• 3.The turn on process maybe longer, because you need connect the module with the Ai-thinker cloud
• 4.Open the serial interface,you can see the serial output,the data can be transfered to A6 module
• 5.If you want to make a call,you can input the phone number via the keyboard,then press the dial key,you need insert the MIC;
• if you want to hang up the phone, please press the dial key again. In the input state,you can long press the dial key or delete key to delete the characters.
• 6.Send message:you can press the message button to send a test message to the phone number
• 7.GPRS data service:you can control the 3 color led and buzzer through the Ai-thinker APP
• 8.DIP switch description:
