If anyone is using the Roger On V2 microphone, the newest firmware is 2.1.48014
I am a user of Phonak Target, but Target does not tell you what firmware version the device has. I was alerted of the availability of a firmware upgrade because I downloaded the app MyRogerMic to my Samsung S23 Ultra.
I downloaded Roger Upgrader and found out I was running version 1.1.44174
I could not find a change log for the firmware
The process was simple. I used my Windows laptop and you just need a USB C cable to connect the microphone to the computer. Follow the instructions
I hope this helps someone
