Via air AT commands
Use the over-the-air AT command to read the current firmware version information.
Open FeasyBlue, select “ Settings “ - “ Parameter Modification “ .
Input password 20138888 .
Enter AT+VER in the custom comand , select this item, and Begin ;
Select the device
Successfully entered the air command mode, read AT + READ successfully, and display the current firmware version information

In the configuration , you can obtain firmware version.
Feasycom Serial Port Tool
Function
● Communicate with the module through UART. ● Communication: scan、connect、send and receive data. ● Configuration: Read/write module parameters.
Serial driver and COMx
Connect the USB port of the Feasycom development board, such as FSC-DB005/DB006/DB008/DB200/other, to the USB port of the computer, the LED indicator light flashes slowly (general program), and the module is searchable and connectable (when the Bluetooth module and other Bluetooth devices establish a Bluetooth connection successfully, the LED will be on normally);
Before development, debugging and use, you need to let the PC recognize the COM port of the device, that is, you need to install the driver. After the driver is successfully installed, you can view it in the PC device manager.
Note: On FSC-DEV-KITS, you can view introductions, user guides, and the serial port drivers you may need for the Feasycom Development Kit you already own.
Necessary configuration
Send AT command
Data transmission communication
TX and Rx
FAQs
OTA upgrade
Q: After clicking “Start Upgrade”, warn “Upgrade failed” ?
A: There is a low probability of occurrence in some mobile phone systems. Just click “Start Upgrade” repeatedly, or exit and re-enter the FeasyBlue and start the upgrade again. This problem will be continuously optimized in the new version.
