User manual Thyone-I
5.9. Secure firmware update
It is possible to perform a firmware update on the module over the UART. The bootloader
checks for the image signature and version before overwriting the exiting image. Please refer
to the chapter
15
for further details.
5.10. Transparent mode
Often legacy systems using a serial cable for communications need to be upgraded to use a
wireless link. In order to support such applications and other applications where simplicity is
preferred over versatility, Thyone-I offers the transparent mode. In this mode the data sent over
the UART is not interpreted by the module (as command). It is blindly forwarded over the radio
link. Similarly, all data received over the radio link are forwarded over the UART. For details
regarding the configuration of transparent mode, please refer to chapter
8
.
5.11. Radio test mode
In order to test the RF performance of the module after integration into a custom design, the
Thyone-I offers radio test modes. Thyone-I implements essential test features out-of-the-box.
• Transmit carrier on a specific channel at a specific transmit power.
• Transmit a random or predefined packet on a specific channel with a given transmit power.
• Receive on a specific channel
Test features come in handy when performing radio compliance tests. Section
7.8
describes
the test mode commands in detail.
This mode intended for design verification and compliance tests only. It should
not be used under normal operation
5.12. Modes of operation
When powered on, Thyone-I can be in one of the following modes of operations,
• Reset A state where the /RESET is held HIGH.
• Bootloader In this mode the module is waiting for a firmware update. (See chapter
15
)
• Command mode This is the standard mode of operation for Thyone-I. In this mode the
module can be configured and controlled using the command interface. (See chapter
7
)
• Transparent mode In this mode, the module acts as a transparent UART-radio bridge.
(See chapter
8
)
• Radio test mode This is a mode meant for radio performance and compliance testing.
