Compatibility:Others
Camera Equipped:No
Model Number:CSR8615
State of Assembly:Almost Ready
Precautions:
1. The module pins are dense and require a good welder foundation. The module is tested before shipment, and will not be returned after Shangxi!
2. CSR Bluetooth module audio is differential output, you need to add op amp or amp circuit to single-ended output (left channel, right channel, audio common).
3. Only the module application data, ie the Bluetooth module specification and the Bluetooth module reference schematic, are provided.
4. BTM05E and BTM870 are difficult to develop, there is no standard program, and other modules (BTM805/815/830/845, etc.) are the default programs. Please refer to the module specification for the default program operation instructions.
BTM815-B Bluetooth audio module, using CSR8615 chip, supports A2DP, AVRCP, HFP, AAC, etc., using 4M SPI FLASH memory chip.
Software Description:
Bluetooth name: BT Speaker
Note: The button is active high (MFB high level is 3.3V, PIO high level is 1.8V)! Another: Here is the PIO port, not the actual PIN pin, you need to check the specification to see the actual PIN foot!
The button description is as follows:
MFB: High level boot, low level shutdown (PIN30 needs low level when the module is powered on, need to do delay circuit when powering on, can't pull up directly, boot automatically enters pairing mode)
PIO6: Amplifier control enable pin (output level 1.8V when audio output is available)
PIO8: Short press play/pause/answer/hang up, long press 1 second to reject the call
PIO1: Short press the previous track, long press the volume minus
PIO0: Short press a song, long press volume plus
Special function description:
PIO8: Press and hold for 3 seconds to force the pairing mode, press and hold for 6 seconds to clear the pairing list.
PIO8 PIO1: Long press for 1 second to enter search TWS mode (CSRA64xxx/QCC300x Bluetooth series only)
PIO8 PIO0: Long press for 1 second to enter the searched TWS mode (CSRA64xxx/QCC300x Bluetooth series only)
PIO1 PIO0: Long press for 1 second to disconnect TWS (CSRA64xxx/QCC300x Bluetooth series only)
