Lithium battery interface. 3.7V to 4.2V. Do not exceed the voltage, otherwise the module will be damaged

8

Volume plus

Short press Volume increase/Long press next track

9

Volume down

Short press volume decrease/Long press previous track

10

On-off key
Long press 2s switch machine;
Play music: short press pause/play;

15

module

Can support BT1026X series/BT1035 / BT1036C/BT1032C BT955 / BT958 and so on

16

Module pin

Module each pin

17

TRBI200

TRBI200 burner interface, empty by default

18

Module reset key

Press the module to reset

19 *

Battery charging/module upgrade

Battery charging in short circuit state, module upgrade/fixed frequency

20 *

Module power supply
Short circuit: Type-C supplies power to the module;
Off: The battery supplies power to the module,
Or charge the battery when the Type-C has input voltage and the “Battery charge/Module upgrade pin” is short circuited

22

Module indicator

The blue light flashes quickly for pairing, and the long light indicates that it is connected. If the green light is steady on, the SPP/BLE connection is successful

Note

The three marked with * can be combined to achieve battery charging, and the maximum current is 200mA. Generally, this function is disabled by default. Not all modules support battery charging.

Quick Start

Take FSC-BT1026C dual-mode Bluetooth audio module and universal firmware as an example to demonstrate the quick operation steps:

(1). Switch the development board to UART serial communication debugging mode:

Switch the USB/UART toggle switch (component number 2) on the development board to the UART

_images/DB200-2-UART-Enable.png

(2). Connect the development board to the PC through a Type-C cable


_images/DB200-1-TypeC.png

(3). After the connection, the PC recognizes the serial port COMx

(4). The module is powered on

Press the module power supply button (component number 20) to switch to Type-C power supply (Down=USB);
Press and hold the on/off button (component number 10) for 2s;
Indicator LED00 (Component No. 21) The blue indicator blinks: The device is powered on

This demonstration, firmware configuration, power-on response configuration data, different firmware may be different, the actual situation shall prevail.


_images/%E4%B8%B2%E5%8F%A3%E5%8A%A9%E6%89%8B-AT%E8%AF%86%E5%88%AB-en.png

Supports the use of modules with AT commands, such as sending AT+VER in response to the firmware version information of the module

(4). Connect the speaker or headphones to the SPK audio output port (component number 5) of the development board through the 3.5mm AUX audio cable.

(5). Scan and connect modules on the mobile phone

Serial port response +HFPSTAT=3 indicates that the HFP protocol is connected (for calls)
Serial port response +A2DPSTAT=3 indicates that A2DP is connected (for music)

(6). Music mode（A2DP）

When the phone plays music, the serial port feedback:
+A2DPSTAT=3 //A2DP connected,Mobile phone playing music
+PLAYSTAT=1
+A2DPSTAT=4
+A2DPSTAT=5 //Media streaming

(7). Call mode (HFP)

When the mobile phone makes a call, the serial port feedback:
+HFPSTAT=3 //Make a call from a mobile phone
+HFPAUDIO=1 //Create HFPAUDIO
+HFPSTAT=4
+HFPSTAT=6 //call active
