The chip itself does not support serial programming. Only the programmer provided by the chip manufacturer can be used for programming. Anxinke independently developed a serial port programming tool, which can be used without an official programmer. The Anxinke bootloader must be burned into the module first. Generally, the Anxinke factory modules and development boards are support serial programming.
- If you use Anxinke TB series development board for development, you can directly connect the development board to the computer via USB.
- If you use Anxinke TB series modules for development, you need to prepare a USB-to-serial module that supports hardware flow control, and connect the Bluetooth module with the USB-to-serial port according to the following table, and then insert the USB-to-serial port into the computer.
| Serial Port | Module |
|---|---|
| VCC | 3V3 |
| GND | GND |
| TX | RX |
| RX | TX |
| RTS | RST |
| DTR | SWS |
SWS is the boot selection pin. Hold low to enter download mode, and hold high to enter operating mode.
After connecting the development board or module to the computer via USB, find its corresponding serial port:
- Windows systems can view the serial port in the Device Manager. Windows
serial port IDs start with
COM. - In Linux systems, check the detected serial ports with
ls /dev/ttyUSB*. - In Mac OS systems, check the detected serial ports with
ls /dev/cu*.
Check the serial port number, modify the DOWNLOAD_PORT line in makefile in
the blink directory, and change the value to the serial port number of the
development board. For example, if you're using Windows and the port number
corresponding to the development board is COM3, the line should read:
DOWNLOAD_PORT := com3
After successfully setting the serial port number, you can use the following commands to burn the firmware to the chip: Burning instructions:
make flash
Telink_Tools.py v0.3 dev
Open /dev/ttyUSB0 ... ... Fail!
If the above error occurs, please check whether the serial port number is set correctly and whether the serial port is in use by another program.
Press the RST button on the development board to reset the development board and start running the firmware that has just been burned.
If you use a single module for development or want to open the serial port, you
can use the make monitor command.
To erase the firmware:
make erase_fw
To erase the entire flash, except the bootloader:
make erase_all
