KT6368A AT Command en v1.0.pdf
KT6368A AT Command
AC6368A Datasheet V1.0.pdfCommon problem:
Question 1:How to distinguish between AT instruction and serial port transparent data transmission? How to know if Bluetooth-compatible is connected?
1. AT command, only valid when Bluetooth-compatible is not connected
2. As long as the Bluetooth-compatible connection is successful, it will enter the
transparent transmission, and the AT command will be invalid.
3. This depends on the STA pin of the module. The output low level is not connected. High level output after successful connection
Question 2:How to determine whether the chip is working properly? And the serial port connection is normal?
1.
At the moment the chip is powered on, pin 2 will output a high level
for 1 second, and then immediately pull it down. So connect an indicator
light to see the status
2.
When the chip is powered on, the serial port will definitely return
information. Pay attention to it, if you don’t receive it, there is a
problem with the serial
Question 3:Do you support modifying UUID, Bluetooth-compatible name and Bluetooth-compatible MAC address?
1. Support to modify the Bluetooth-compatible name and Bluetooth-compatible MAC address
2. Of course, it also supports AT command to read. Uuid does not support customers' own modification at the moment, it will be added later.
