New Bluetooth firmware for CYW43455 (3B+, 4B, CM4)

Mon Nov 23, 2020 5:42 pm

It's new firmware season at the moment, and Cypress have provided an update that solves the BLE connections problems of the last release: https://drive.google.com/file/d/1DVOtBj ... sp=sharing

You can install it with:

Code: Select all

$ sudo mv /lib/firmware/brcm/BCM4345C0.hcd{,.bak}
$ sudo cp BCM4345C0_003.001.025.0171.0339.hcd /lib/firmware/brcm/BCM4345C0.hcd
Reverting to the original is simply a case of:

Code: Select all

$ sudo mv /lib/firmware/brcm/BCM4345C0.hcd{.bak,}
Please leave any feedback about the firmware in this topic: viewtopic.php?f=36&t=292111
