Description

When using the iPad in order to monitor the battery, no data from the BLE sensor get displayed.

Some bluetooth related errors can be found in the system log:

bluetoothd[375]: Failed to open RFKILL control device
bluetoothd[375]: Unable to open adapter storage directory: /var/lib/bluetooth/48:EB:62:C6:26:B5

"rfkill" command in poc-service script fails the same way and the reason seems to be that file /dev/rfkill doesn't exist.

I tried to reinstall the package providing "rfkill" (util-linux) but it didn't create the missing file.

On my openSUSE machine I see there's a driver named "rfkill" which isn't present on the redpesk image, could be the root cause maybe...

From what I read on the "rfkill" topic, it seems it can be either a module or an executable. This has to be decided when building the Linux kernel by setting variable CONFIG_RFKILL to either 'm' or 'y'. On the redpesk image I use, /proc/config.gz indicates CONFIG_RFKILL wasn't set at all so I guess setting it to 'y' and rebuilding the kernel should fix the problem.

Thank for your report and your analyses. Indeed, our new solidrun image has a missing driver. We are adding this one, and we will take the opportunity to integrate the new Solidrun patches which improve the BLE activation on your solidsense board
