ETRX35x Development Kit
12 Firmware upgrades
If required, the firmware of the ETRX35x modules can be upgraded serially as well as over the air.
(Note: at the time of writing over-the-air upgrading is not yet available.)
12.1 Firmware Upgrades via Serial Port
In order to upgrade the firmware of the ETRX35x module using the serial bootloader, issue the
“AT+BLOAD” command either by typing it in, or by pressing the respective button in the “Module
Control” group of the Telegesis Terminal Application.
Alternatively the button labelled “Bload” can be pressed on the development board whilst the reset
button is pressed and released.
After entering the bootloader, the connection parameters need to be changed to 115200bps, 8
data bits, 1 stop bit, no parity, no flow control (providing that it is not already set to these values).
This is achieved by pressing the ‘Disconnect’ button, changing the settings and then pressing the
‘Connect’ button (if only the connection speed needs to be changed disconnecting and
reconnecting may not required, depending on your PC’s operating system).
After pressing ‘Enter’, the bootloader menu will be shown in the terminal window as shown in
Figure 23.
