Bluetooth chips question

Yep there is a guy here called Boki, really helpful dude, and we've help him a lot, sort of

Very funny :-)

A less flippant replay is to suggest a module (using a bare chip is *not* for the fainthearted). Google for somewhere to buy a module with programming support.

Typically, you get a module with power, digital and perhaps analogue I/O, antenna and supply connections. You then somehow put custom software on this module (or add a microcontroller on the board and speak to the bluetooth module using some serial protocol). Simple as that! Builing your own module is tricky. Very.

A bluethooth transciever is a RF chip running in 2.4Ghz ISM band. Except the transciever itself you need also a PA and probably a microstrip antenna. It's a big project and require the availability of RF tools as spectrum analyzer, eventually a network analizer for antenna caracterisation and a lot of time, base knowledge and software (of couse it needs some logic too...) There are many producers of bluethooth transcievers, most of them are keeping designs on secret and require a NDA signed by an user company. If you are just an amateur will be difficult. So, if you don't match all criteria above, better play with zigbee, it's easier.

Please note that it's 'analyser'. The spelling you use indicates that the network is fundamentally inserted.

TDK sells a ready-to-go kit which implements a bluetooth serial interface.

Is there some rule about the 's' and 'z'?

I didn't notice that. Yes, 'analyser' is usually used in British English, and 'analyzer' in US English. There are no rules; it's all down to usage.

But in general, 'z' is correct, except for a few words, such as 'comprise', 'surprise' and 'advertise'. Apart from those, the 's' spelling was invented in Britain by some newspaper editors in the 1920s and isn't etymologically correct.

I normally use 'z', because it's used in IEC standards.

It's not the s or z. It's the difference between anal and analyse.

That would be Ezurio now.

I used "analizer" because that is called in romanian language, english is just a language I've learned at school, 25 years ago. Of course it looks in english "analyser" is the most frequently used.

greetings, Vasile

A lot of FSU dictionaries have errors. Often the first English word is one which is never used. Search for the meaning of 'Anal'.

Phillips BGB203/1 SIP Bluetooth Chip, with a surface mount 2.4Ghz Antenna?

Almost all you need, take a look at the shortform datasheet. [Google]

Oh warning, tiny 7x8mm HVQFN chip :)

Gack! It's got a 32-bit ARM processor with 268k of flash and 40k of RAM in that little package. The new 8051?

Best regards, Spehro Pefhany

do you know where the full datasheet is? can't find it anywhere, thanks

The shortform really should be all you need.

I'm pretty sure the units available from Digikey only have the SPP (Or whatever their own brand of the acronym is...) profile on it.

I should probably connect up the JTAG and see what else I could do with it....when I have time :(
