The lora development suite (mac download) on the link you provided contains a newer version of the java tool in Applications / LoraDevUtility folder but it has the same issue that @jsperri mentionned.

The java preferences for mac are stored in ~/Library/Preferences/ā¦ but I could not find anything related to fed or dfu
Seems that somebody else already tried to fix this for linux but Microchip is the only one who can fix this unless they make the source code available.
@kersing Is there an issue tracker where we can report and follow up on LoRa Development Suite bugs?
@BoRRoZ Thanks. Your upload kept me going ! I could neither make it at 57600 nor even at 19200. Luck struck only at 9600. Huh !!
Hope this helps someone.
Hey, is it possible to modify this firmware (1.0.1), Iām not talking about the hex code but is there any possibility to find the source code this hex file was built from ?
I have a RN2483 on a bee (Sodaq Mbili). But TEST0 and TEST1 are not on the header. Is there a way to update my two (bricked) beeās then? I have a Pickit3.
For those looking for version 1.0.3 of the RN2483 firmware, the hex file is embedded in the SODAQ firmware updater. Just take the part between the curly braces ( { and } ), remove the double quotes and comma at the end of the line and save with .hex extension.
Resulting file should contain:
:10030000D7EF01F0FFFFFFFF5A82FACF2AF0FBCFB1
ā¦ skipping a lot of lines ā¦
:00000001FF
The result can be used to update using the serial port. (Software for updating can be found in the LoRa Development Suite, available on the Microchip website)
if you see the exception(s) āā¦Folder parameter must be a valid folderā¦ā:
add the path to some valid folder on your system to the files
~/.java/.userPrefs/dfu/prefs.xml
~/.java/.userPrefs/fed/prefs.xml
~/.java/.userPrefs/toplevel/prefs.xml.
In my case, all 3 prefs.xml are the same actually. Example prefs.xml:
I tried using the same setup as you replacing the path with my username but it still having the same folder error. Is there anything that I could miss out?
I upgraded to firmware V1.0.3 and tested with sys sleep command. It doesnāt work as I expected, so I dont know if they fixed this issue with new firmware.
When I sent sys sleep 86400000 to rn2483. It replied āinvalid_paramā, and then āokā, and later āinvalid_paramā. It kept going like that. Can someone confirm this one or did I miss something ?
The invalid_param response is caused by the āUUUUā characters you used to wake the device in the previous attempt. Only one 1 needed, additional ones will be in the command buffer resulting in the command looking like
āUUUUUsys sleep 86400000ā which the module does not recognize to be a valid command.
You can resolve this on two ways:
just send one U
if you want to send multiple (not a bad idea), send an additional line termination ā\r\nā as well to clear the command buffer (this will get you an invalid_param response, just read it and ignore it)
BTW. There is no need to post screen shots of putty output, you can just cut-and-paste the contents of the terminal window into your message. This allows the forum to index the contents of the screen shot as well.

Hi,
Iām trying to update the firmware of the TTN Node for consumption problem (The Things Node Battery consumption)-
Iām not an experienced user, looking at this interesting thread I try the following steps:
Connect the TTN node to a workstation (ubuntu 64 bit 17.10) USB port
Launch the LoRaDevUtility by $ java -jar ./LoRaDevUtility.jar
The LoRaDevUtility GUI show a āFinding Devicesā for about a minute without result
in the meantime the shell shows:
Trying to Connect: /dev/ttyACM0
Connection Successful
Disconnection Successful
Tool List Refereshed
No Server in List
Next, when I try āModule-Boot Load Recoverā from the menu I get and after a while it come back to the home GUI.
In the meantime the shell shows:
Trying to Connect: /dev/ttyACM0
Connection Successful
Tool List Refereshed
No Server in List

So I imagine the tool is able to connect to the device, but there is some problem to set/get information from it.
Do you have any suggestion about this issue ?
Thanks
and after a while it come back to the home GUI.
