BTM830 Bluetooth audio module, using CSR8630 chip, supports A2DP, AVRCP, AAC, etc., using 128K EEPROM memory chips. Precautions 1. The module pin-intensive, the need for better welder basis. Module test before shipment, shall not be returned later on the tin! 2. CSR Bluetooth module audio differential output, the need to increase the op amp or amp circuit is converted into a single-ended output (left channel, right channel, audio common). 3. To provide application data only module that Bluetooth module Bluetooth module specifications and reference schematics 4. BTM05E, BTM870 development more difficult, no standard procedures, other modules (BTM805 / 815/830/845, etc.) as the default program. Default program operation description see modules specifications. Software Description: Bluetooth Name: BT Speaker Key instructions are as follows:PIN30 (MFB): high-level boot, low-level shutdown (module power, PIN30 need to be low, power-up delay circuit to be done, can not pull up, boot automatically into pairing mode)PIN1 (PIO6): power amplifier control enable pin (with audio output, the output high level 1.8V)PIN2 (PIO8): Press to play / pause / answer / hang up, press and hold for 1 second to reject the incoming callPIN3 (PIO1): short press the last song, long press the volume downPIN4 (PIO0): Short press the next song, long press the volume plus Special Features:PIN2: Press and hold for 3 seconds to force into pairing mode, press and hold for 6 seconds to clear the pairing listPIN2 + PIN3: Press and hold for 1 second to enter search TWS mode (CSRA64110 / CSRA64210 / CSRA64215 Bluetooth series only)PIN2 + PIN4: Press and hold for 1 second to enter the searched TWS mode (CSRA64110 / CSRA64210 / CSRA64215 Bluetooth series only)PIN3 + PIN4: Press for 1 second to disconnect TWS (CSRA64110 / CSRA64210 / CSRA64215 Bluetooth series only)
