Firmware update fail
« on: 2014-12-10, 15:39:05 »
Good morning all,

I have a pair of units with Firmware 2.32 that were never placed in service. Today I tried to update the firmware via the USB cable using the latest Microbit Setup Manager and the latest firmware 2.81. I can connect to the unit in Manager and can retrieve the HW and Firmware info. I open the .bin file and attempt to update and after 10 seconds Manager responds with Update Failure -1.

I'm using Win XP 32 bit. I tried Firmware 2.54 (the oldest I can find) with the same result.

Any thoughts?

73,

Paul

It might be that that version is so old that it has a bug which could make USB upgrading impossible. A workaround would be to use the web interface instead.

Good day Jan,

I was able to upgrade through the web server. Thank you. I have the units configured and passing audio in both directions.

I have units that are hardware version 6 and I have noticed that when set up for two channel receive audio, there is about a 7 dB difference in output levels with the same input level. Is this correct?
