User manual Thyone-I
8. The transparent interface
In this mode Thyone-I acts as a radio bridge, any data received on the UART will be sent via
radio. The receiver may operate in command mode or also in transparent mode.
The main application for the transparent mode is a serial cable replacement.
For new system designs we highly recommend using the command mode.
8.1. Entering the transparent mode
The transparent mode can be entered using one of the following methods:
• when
is configured to 0x00 and
pin is HIGH during boot-up
• when
is configured to 0x01 using the command
• when
is configured to 0x02
8.2. Leaving the transparent mode
The transparent mode can be left using one of the following methods:
• when
is configured to 0x00: performing a module reset and holding
pin to LOW during boot-up
• when
is configured to 0x01: performing a module reset
• when
is configured to 0x02 and
is enabled (default),
by using the escape sequence
(default: "+++").
8.2.1. Transparent mode escape sequence
The transparent mode escape sequence requires a pause of > 50 ms before and after the
configured 3 byte sequence (default "+++") to be accepted.
A pause in between two consecutive bytes of the escape sequence shall not be larger than a
byte duration or 5 ms - whichever is smaller.
