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): image Do you know what's the problem?

Thanks in advance, Tobi

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

inpoison commented 4 years ago

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 commented 4 years ago

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.
