I have a raspberry pi 3 with Jessie lite (10-APR-2017) that worked perfectly until yesterday. Now WIFI & Bluetooth don't work anymore - LAN is OK.
dmesg
shows mmc1: error -110 whilst initialising SDIO card
I re-imaged the SD-card with the newest Jessie Lite (05-JUL-2017)
dmesg
shows mmc1: error -110 whilst initialising SDIO card
hcitool scan
shows Device is not available: No such device
Don't know what the problem is...
