Sunday 17-10-29 I A Bluetooth Problem fixed

 

I have a natty little Samsung Tab E that I should make more of, and I also acquired a Samsung bluetooth keyboard (EE-BT550) a while ago - my plan was to use them together to take quick notes and write quick blogposts as & when the need took me. As you can see from the sporadic entries in this blog, I’ve not quite mastered the art of that, but I have a few thoughts roiling around in this sparsely-populated head of mine.

Anyway, I got up this morning, made a cup of tea and prepared the tablet and keyboard. The Youngest was in the living room watching YouTube or somesuch without headphones and I didn’t want to be driven mad by mindless drivel at such an early stage in the day. So I tried to pair the tablet and keyboard, without success. After many times trying to enter the passcode given by the tablet, I realised it wasn’t going to work. The tablet was timing out even before I could tap in the six-digit code, and even when I did, the tablet was telling me that the passcode was wrong.

Then I thought outside the box a bit, and wondered how I could isolate the problem. I tried pairing the keyboard to my phone, and could do that. I fished out a second keyboard and could pair that to the tablet. So eventually, I was none the wiser. Both the tablet and the keyboard could pair, just not with each other. Then I had a doubt; I’d rooted the tablet a while ago, could that be having some impact? I knew that the ROM I’d installed was supposed to be stock with root and SuperUser access, but sometimes not all functionality is replicated fully. So I started looking into how to return to stock, and I found a guide which suggested using Odin and a downloaded stock ROM. The trouble was that it looked like it was going to take more than an hour to download the ROM, and then there was no guarantee that I’d picked the right one for my tablet. So I installed Kies instead, and hooked up my tablet to the PC. It guided me to install Smart Switch, but eventually I was able to re-initialise the tablet and install official stock software. Then I tried to pair my Bluetooth keyboard again, and I could manage it. So I think that maybe I chose the nuclear option, and maybe I didn’t need to unroot and re-install stock firmware, but it might have been the fact that I had a custom recovery installed that was throwing the Bluetooth out.

Anyway, now I can pair and type away to my heart’s content. Will it happen? Probably not, but who knows.

TTFN.
