I need to disable ERTM because of Bluetooth connection drops
CPU: dual core Intel Core i5-4300M (-MT MCP-)
speed/min/max: 2780/800/3300 MHz Kernel: 5.15.49-1-MANJARO x86_64 Up: 6h 18m

sudo /usr/lib/bluetooth/bluetoothd -n -d
[sudo] password for axe:

But according to the arch wiki this is no needs anomore after 5.12th kernel.
5.15.49-1-MANJARO
I have above then have drop too
To solve this issue ;
sudo echo 1 > /sys/module/bluetooth/parameters/disable_ertm
bash: /sys/module/bluetooth/parameters/disable_ertm: Permission denied
also,
pwd
/etc/modprobe.d
cat bluetooth.conf
options bluetooth disable_ertm=Y
or
options bluetooth disable_ertm=1
Tried old solutions but still getting connection drop.
What should I do?
Do you agree with disabling ertm is not required no longer
I didn’t understand that kind of nonfunctional? it can’t be use (can be use with***–force***) or totally removed from kernel.
Can I force it?
