Weird responses from A9G

[inpoison]

Hi,
I wanted to the test the board with example "Get GPS Location" mentioned in the wiki.
Unfortunately, the responses from the A9G seem to be weird (and not successful):

Do you know what's the problem?

Thanks in advance,

Hi，
Do you power the board via a 3.7V lipo battery? Battery must need.

[inpoison]

Yes, a 3,7V (600mAh) battery is plugged in and the orange LED is on. The standard baud rate to communicate with the A9G is 115200, right?

[IOT-MCU]

yes, the default baud rate is 115200.
It seems that the A9G can not power on by the ESP-12S. Please down load the ESP-12S_A9G_TEST.ino to test the board again. Before shipping, i had test all the board.
If it can not working, please sent me more detail, Thanks.
