Precautions
1. The module pins are dense and require a good welder foundation. Module pre-shipment test
2. CSR Ble 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 Ble module specification and the Ble module reference schematic, are provided.
4. Support app control, you can view Ble information and modify EQ function
Software Description
Ble 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!
|
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
