Remote Control App UART Function

Data format used for UART function.

Explanation of data format used in the UART function of Remote Control App (App_IO).

Digital Input and Output

Outputs the state of the received input signal.

#	Data	Description	Remarks
	`char`	Header	`:` only
0	`uint8`	Source Logical Device ID
1	`uint8`	Command Number	`0x81` only
2	`uint8`	Packet Identifier	`0x0F` only
3	`uint8`	Protocol Version	`0x01` only
4	`uint8`	LQI	`0`-`255`
5	`uint32`	Source Serial ID	`0x8???????`
9	`uint8`	Destination Logical Device ID
10	`uint16`	Timestamp	64 counts per second, MSB is internal flag
12	`uint8`	Relay Count
13	`uint16`	Digital Signal	Corresponds to `Ix` from LSB, `0` is High
15	`uint16`	Digital Signal Mask	Corresponds to `Ix` from LSB, `1` means valid
17	`uint16`	Digital Signal Flag	Corresponds to `Ix` from LSB, `1` means interrupt
19	`uint8`	Unused	For internal management
	`uint8`	Checksum	LRC8
	`char`	Footer	CR (`0x0D`/`'\r'`)
	`char`	Footer	LF (`0x0A`/`'\n'`)

Parent and repeater apps (v1.2 and earlier) do not support this format.

There is a reported bug with TWELITE GOLD App_IO v1.3.2 where transmission commands may not work in some cases.

The cause is under investigation. For TWELITE STICK, please use App_Wings v1.3.2 (TWELITE Apps unified version is also available).

Option bit 0x00010000 Force enable reception on child device must be enabled to activate reception function on child devices.
Option bit 0x00020000 Stop UART output on input change can be enabled to ignore Input Change Messages.
Communication between child devices is possible. Assign unique logical device IDs to child devices to identify them.
