We are encountering an issue with Bluetooth Low Energy (BLE) adapter. The device works as expected on PC running Ubuntu Desktop, but when connected to my Raspberry Pi running Ubuntu Server, it is not functioning correctly. When we run the ‘hciconfig’ command on the Raspberry Pi, the adapter shows an address of 00:00:00:00:00:00 and its status is listed as “DOWN”. Despite this, the adapter is not detected or usable for Bluetooth operations on the Raspberry Pi. Based on our observations, we suspect this may be related to a firmware issue or a compatibility problem with Ubuntu Server on the Raspberry Pi. The adapter works fine on desktop system, but not on the Raspberry Pi. Please provide any guidance, firmware updates, or troubleshooting steps to help resolve this issue on the Raspberry Pi? Your assistance would be greatly appreciated.
