Chinese Heater Half Duplex Serial Data Sending Tool
Connects to the blue wire of a Chinese heater, which is the half duplex serial link.
Sends and receives data from hardware serial port 1.
Terminology: Tx is to the heater unit, Rx is from the heater unit.
Typical data frame timing on the blue wire is:
__Tx_Rx____________________________Tx_Rx____________________________Tx_Rx___________
This software can connect to the blue wire in a normal OEM system, detecting the
OEM controller and allowing extraction of the data or injecting on/off commands.
If Pin 21 is grounded on the Due, this simple stream will be reported over Serial and
no control from the Arduino will be allowed.
This allows passive sniffing of the blue wire in a normal system.
The binary data is received from the line.
If it has been > 100ms since the last blue wire activity this indicates a new frame
sequence is starting from the OEM controller.
Synchronise as such then count off the next 24 bytes storing them in the Controller's
data array. These bytes are then reported over Serial to the PC in ASCII.
It is then expected the heater will respond with it's 24 bytes.
Capture those bytes and store them in the Heater1 data array.
Once again these bytes are then reported over Serial to the PC in ASCII.
If no activity is sensed in a second, it is assumed no OEM controller is attached and we
have full control over the heater.
Either way we can now inject a message onto the blue wire allowing our custom
on/off control.
We must remain synchronous with an OEM controller if it exists otherwise E-07
faults will be caused.
Typical data frame timing on the blue wire is then:
__OEMTx_HtrRx__OurTx_HtrRx____________OEMTx_HtrRx__OurTx_HtrRx____________OEMTx_HtrRx__OurTx_HtrRx_________
The second HtrRx to the next OEMTx delay is always > 100ms and is paced by the OEM controller.
The delay before seeing Heater Rx data after any Tx is usually much less than 10ms.
But this does rise if new max/min or voltage settings are sent.
**The heater only ever sends Rx data in response to a data frame from a controller**
For Bluetooth connectivity, a HC-05 Bluetooth module is attached to Serial2:
TXD -> Rx2 (pin 17)
RXD -> Tx2 (pin 16)
EN(key) -> pin 15
STATE -> pin 4
This code only works with boards that have more than one hardware serial port like Arduino
Mega, Due, Zero, ESP32 etc.
The circuit:
- a Tx Rx multiplexer is required to combine the Arduino's Tx1 And Rx1 pins onto the blue wire.
- a Tx Enable signal from pin 22 controls the multiplexer, high for Tx, low for Rx
- Serial logging software on Serial0 via USB link
