For the remote control project, I'm still undecided on whether to use Wi-Fi or Bluetooth LE for connectivity.
Bluetooth LE is still a quite new technology and there aren't many manufacturers of Bluetooth LE chips and modules. Read this article for a good guide to the availabe chips and modules (most of which seem to be based on TI's CC2540 chip).
There's no way I'm going to mess around with the chip itself – impedance matching of the antenna trace and shielding and whatnot are better left in more capable hands. So I'll be using a complete module. And Bluegiga's BLE112 seems nice: it's based on the CC2540 and there's plenty of documentation on Bluegiga's Tech Forum (you need to register to access the documentation which if both free and easy – no NDA's or anything).
However… There are not a lot of distributors of the BLE112. Mouser has it. But it "may require a licence to export from the United States". But I went ahead and ordered a couple of BLE112 modules and a CC DEBUGGER (which is necessary for configuring the BLE112 module).
It turns out that Mouser was not able to export the CC Debugger to Denmark and for the BLE112 I had to fill out an "Customer End-User Certificate" so they can decide whether I'm eligible for getting my hands on that kind of technology or not. (Strangely enough, Bluegiga is based in Finland which is practically Denmark's next-door neighbors.)
I did, however, manage to get a CC Debugger from the Danish branch RS Components instead (since they ship from Europe there is no export hassle) and I'm still waiting to hear from Mouser…
