Description:

Tips: mini GA6 has been upgraded to mini GA6-B! The differences between GA6 and GA6-B are as follows:

Hardware changes:

1. The previous version of Pwr requires a pull-up boot, and now it is changed to a pull-down boot.
2. The blue indicator was originally connected to TXD, but it is now connected to the NetLight pin of the network indicator.
3. The size is unchanged, the Mini board pin is compatible with the old GA6 V2.0

AT firmware changes:

The original transparent transmission setting command is canceled ---> AT + KCDATAMODE controls whether the server successfully enters transparent transmission mode

Replace with: AT + CIPMODE to control whether the server successfully enters the transparent transmission mode

For other minor changes, please check GA6-B AT instruction set V3.03

   ---------------- Advantages of GA6-B module -----------------

Wide area coverage: GPRS has good coverage in 34 provinces, and it is a popular 2G communication standard. Basically, GPRS wireless Internet access is available in places where mobile phones can make calls;
 
Always online: As long as the GPRS application is activated, it will stay online all the time, similar to the wireless dedicated line network service.
 
Billing by volume: Although the GPRS service stays online all the time, you do not have to worry about the cost; you only charge when you generate communication traffic.
 
High-speed transmission: At present, GPRS can support a peak transmission rate of 85.6Kbps, and the theoretical peak transmission can reach more than 100 Kbps.
 
Cheap price: Compared with the SIM series module, the price is only half of it. Greatly reduced
Entry threshold for IoT devices;
 
With its small size, low power consumption and wide operating temperature range, GA6 is the ideal solution for M2M applications, suitable for automotive, industrial and PDA, personal tracking, power environment detection, wireless POS, smart metering and other M2M applications To provide
GSM / GPRS short message, data transmission and voice service.
