Updating WISA firmware Transmitter 1 / Beolab 17

6 replies
  Anyone flashed firmware of  Beolab Transmitter 1 ? I recently bought a ex store demo pair of 17’s and a Transmitter 1 . The 17’s came from a dealer and probably not really old stock. The Transmitter 1 was from ebay and hard to determine it’s age. According filenames and dates from the update software (to download from B&O support site on a USB flashdrive first) latest Wisa firmware for 17’s dates already back to 2018. Last Firmware from Transmitter 1 is from 2020. Amyway, followed all the instructions on B&O support site for the update process but all the described sequences of flashing LED’s on not Transmitter 1 and Beolab 17 are not observed, with the USB flashdrive inserted in Transmitter 1 , it just does it’s normal boot sequence as well do the 17’s.   I think this means both Transmitter 1 and 17’s both have latest firmware onboard, but there is no way to verify that!! Don’t have any complaints by the way, Core is powerlinked to Transmitter 1 wireless feeding the 17’s and the connection is just rock solid. No hickups, delay, weird noises, it just works. Did not expect that to be honest :) Anyone experience with this process?
There is a file on the USB thumbdrive that logs the activity. You can see if the speaker was skipped or updated and what the firmware of the speaker/receiver is. I saw a different behavior for Receiver 1 units that were being updated compared to ones that already had the recent firmware. I found it to be good practice to have just one speaker/receiver plugged into power at a time for the firmware update cycle so that I could see what was happening for that specific Receiver 1.
hello your issue is not doubtable , might be my answer helps you To make a software update of your Beolab 18 via Beolab Transmitter 1,  The product status indicator flashes green during the software update.
I will give it another try during the weekend. Thanks all.  
I wonder if you have done it successfully?
So I did very similar to you - buy a used pair of BL17s from a B&O Dealer. Requested that the BL17s were flashed to the latest software before dispatch. (so i didn't have to buy a BeoTrans1).
  1. How can I tell if they were really flashed to the latest SW? No proof?
  2. What difference did it make? Don't know...cant compare.
  3. What was in the SW update? I heard anecdotally it was  for WISA improvements only....no change to the Sound and as I'm wired configuration only.......
