Then boot into SFOS and install these two packages:

• bluetooth-rfkill-event-hciattach
• broadcom-bluetooth-bluez5

Then amend /etc/bluez5/bluetooth/main.conf file and at [GATT] section, set Channels = 1. Like

Code:

# Number of ATT channels
# Possible values: 1-5 (1 disables EATT)
# Default to 3
Channels = 1

Reboot again and after this, all apps and Bluetooth should work as before.
