Hello,
we have to implement a DietPi Linux on an elder available hardware platform (NanoPi neo) including a D52MD2M8IA for bluetooth.

The module is wired to UART1 of the Nano Pi which we enabled. The power pin was also set and the tty attached, see below.

echo "203" > /sys/class/gpio/unexport 2> /dev/null || true
echo "203" > /sys/class/gpio/export
echo "out" > /sys/class/gpio/gpio203/direction
echo "0" > /sys/class/gpio/gpio203/value
echo "1" > /sys/class/gpio/gpio203/value # This sets power to ON

/usr/bin/btattach -B /dev/ttyS1 -S 115200

Bluetooth service is running but trying to use the D52MD2M8IA module we get:

root@DietPi:/lib/systemd/system# bluetoothctl
Agent registered
[bluetooth]# power on
No default controller available
[bluetooth]#

Any hints how the module might be enabled?

After trying a lot we are now pretty desperate and run out of ideas on how to get it to work.

We would be very grateful for any help.

Hi DrCWO,

I'm facing the same problem. Did you find a solution?

Hi Whitefish,
I was not able to solve it.

I ended up adding a USB BT-dongle and that worked.

Hi Whitefish,
I was not able to solve it.
Ensure that the required kernel modules are loaded, and the device tree overlay for UART1 is correctly configured. While looking for a trustworthy dissertation writing service, I came across https://letsgradeit.com/best-dissertation-writing-services/ website. This site's reviews changed the game! It was the thorough list and objective assessments that enabled me to make an informed choice. Because of the site's easy-to-use layout, I was able to compare services and find the ideal fit for my needs quickly. Bravo to the group for gathering such important data. I avoided possible headaches, and wasted time, and effort. To anyone navigating the difficult landscape of dissertation writing services
