RaspberryPi 1 B / TP-Link Bluetooth 5.0 Nano USB Adapter UB500
« on: December 16, 2023, 10:05:29 AM »
Hello,

i am trying to get the "TP-Link Bluetooth 5.0 Nano USB Adapter UB500" working with my old 1B. I have just upgraded my RaspberryPi from an age old squeezeplug installation to pCP, to make the BT dongle work, but i am having trouble.

dmesg gave me this:
Code: [Select]
[  127.464764] Finished piCorePlayer v8.2.0 startup.
[  531.954391] Bluetooth: Core ver 2.22

[  532.172758] Bluetooth: hci0: RTL: firmware file rtl_bt/rtl8761bu_fw.bin not found

So i guess there is no driver for the device? I have been searching for information for the last three hours but i am out of my wits, my Linux knowledge is hardly existant. Any help to would be greatly appreciated.

Did you just try to google search "picoreplayer rtl8761bu"  seems the information is the number 1 result.

Otherwise, support for piCorePlayer is not done on this site.  Please see their documentation for help and support sites.
