|
||||
=== "Sleep Mode 1"
|
||||
- **Operating state**: Both TX/RX are in sleep, WiFi is off, TX and RX BLE are working
|
||||
- **How to enter sleep**:
|
||||
- The application actively calls the Sleep interface
|
||||
- Automatically enters after detecting no I2S data for a period of time
|
||||
- **Wake-up method**:
|
||||
- UART/GPIO interrupt wakes up TX → TX wakes up RX
|
||||
- UART/GPIO interrupt wakes up RX → RX wakes up TX (bi-directional wake-up)
|
||||
- **Current**:
|
||||
- **Operating State**: TX/RX both sleep, WiFi off, TX and RX BLE operational
|
||||
- **Sleep Entry Method**:
|
||||
- Application actively calls Sleep interface
|
||||
- Automatically enters after detecting no I2S data for a period
|
||||
- **Wake-up Method**:
|
||||
- UART/GPIO interrupt wakes TX → TX wakes RX
|
||||
- UART/GPIO interrupt wakes RX → RX wakes TX (bidirectional wake-up)
|
||||
- **Current Draw**:
|
||||
- Unidirectional wake-up: TX ≤1mA, RX ≤3mA
|
||||
- Bidirectional wake-up: TX ≤3mA, RX ≤3mA
|
||||
|
||||
|
||||
=== "Sleep Mode 2"
|
||||
- **Operating state**: TX WiFi does not sleep, RX WiFi sleeps, TX/RX BLE are off
|
||||
- **How to enter sleep**:
|
||||
- The application actively calls the Sleep interface
|
||||
- Automatically enters after detecting no I2S data for a period of time
|
||||
- **Wake-up method**:
|
||||
- The application calls the playback interface (TX automatically wakes up RX)
|
||||
- RX is automatically woken up when I2S data is detected
|
||||
- **Current**: RX ≤1mA
|
||||
- **Operating State**: TX WiFi does not sleep, RX WiFi sleeps, TX/RX BLE off
|
||||
- **Sleep Entry Method**:
|
||||
- Application actively calls Sleep interface
|
||||
- Automatically enters after detecting no I2S data for a period
|
||||
- **Wake-up Method**:
|
||||
- Application calls playback interface (TX automatically wakes RX)
|
||||
- Automatically wakes RX when I2S data is detected
|
||||
- **Current Draw**: RX ≤1mA

## Q3: What is the WIFI and BT chip architecture of the module?
|
||||
## Q3: Module WiFi and BT chip architecture
|
||||
|
||||
A single SoC integrates both WIFI and BT functions.
|
||||
Uses a single SoC chip integrating WiFi and BT functionality.

## Q4: Does it support online TX/RX switching?
|
||||
## Q4: Does it support online TX/RX conversion?
|
||||
|
||||
### Support status:
|
||||
- Supports online TX/RX switching in WIFI mode
|
||||
### Support Status:
|
||||
- Supports TX/RX online conversion in WiFi mode
|
||||
- BT mode limitations:
|
||||
- SoC only supports BLE5.0
|
||||
- Does not support Classic BT
|
||||
- Cannot transmit audio via mobile phone Bluetooth
|
||||
- SoC only supports BLE 5.0
|
||||
- Does not support Classic BT
|
||||
- Cannot transmit audio via mobile phone Bluetooth
|
||||
|
||||
### Working mode description:
|
||||
### Operating Mode Description:
|
||||
|
||||
=== "**TV Mode**:"
|
||||
- The transmitter box is WIFI TX
|
||||
- The receiving speakers are dual RX (left/right channels)
|
||||
- Transmitter box is WiFi TX
|
||||
- Receiver speakers are dual RX (left/right channels)
|
||||
|
||||
|
||||
|
||||
|
||||
=== "**BT Mode**:"
|
||||
- Left speaker:
|
||||
* Receives mobile phone signal via BT
|
||||
* Simultaneously acts as WIFI TX to transmit to the right speaker
|
||||
- Right speaker: pure WIFI RX mode
|
||||
- Acts as BT receiver for mobile phone signal
|
||||
- Simultaneously acts as WiFi TX to transmit to right speaker
|
||||
- Right speaker: Pure WiFi RX mode

## Q5: Bluetooth TWS function implementation
|
||||
|
||||
- **Native Bluetooth TWS is not supported**
|
||||
- **Alternative solution**:
|
||||
- In BT mode, the left speaker (with IR receiver) acts as TX
|
||||
- Transmits the right channel to the right speaker via TWS
|
||||
- The right speaker (without IR receiver) acts as RX to receive the TWS signal
|
||||
- **Does not support** native Bluetooth TWS functionality
|
||||
- **Alternative Solution**:
|
||||
- Left speaker (with remote control receiver) acts as TX in BT mode
|
||||
- Transmits right channel to right speaker via TWS method
|
||||
- Right speaker (without remote control receiver) acts as RX to receive TWS signal
