update firmware to nodes does not work

[sietse]

Hello,
trying to update the firmware using the lps configuration tool. But after entering the needed dfu file and connecting the usb while pressing the DFU button, the update-button in the app stays gray. So I cannot update the firmware.
Tried this several times and with multiple nodes.

Configuring the nodes does work however!

What can I do?
Thanks in advance,

PS. Doing this from linux.

Hi,

From linux it could be a right problem, if so launching the tool with 'sudo' will solve the problem. If you need to update often and prefer not to launch the tool as root with sudo you can add a usev rules file similar to the one used by Crazyradio.

Thanks, updating the udev rules works!
