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
