I am looking at developing an industrial product which will have BT.
Obviously there are numerous ways to do it, with any microcontroller and one of the BT modules.
My preference is towards the Atmel ATmega128 because we have some other projects, currently using a Hitachi H8/323, which will eventually be migrated to that. Atmel, along with Microchip, seems to be the only company committed to a long term embedded business, with a decent continuity of development tools.
But I wonder if anyone here has done it before and found some really easy way.
Preferably the software should be written in C, maybe with a bit of assembler for things like interrupt service routines (the product will also have an RS485 port, 1200-115k baud) and we will need to write some simple PC software to send out with it, for testing it.
I presume that the BT profile would be something like an FTP server - it is for transferring values from an A-D converter.
Currently we use a TI A-D which is 12-bit, with an I2C interface, and we do actually need the 12 bits (not 10 bits plus rubbish which is usually the case with on-chip A-D converters).
I'd much appreciate any pointers to some low cost proven stuff which is widely used.
