D52MD2M8IA with DietPi

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.

best dr. C.-W. Oehlrich

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
