Hello Dear,
We are a team of experts with a cumulative experience of more than 50 years in the field of embedded systems, programming, electronics and prototype development. We work in Smart Grid, wireless, telecommunications and medical.
We can use a BTLE SoC like cc2540 or cc2541 to achieve BTLE connectivity along with the 8051 internal core. Fortunately we have the cc-debugger for programming the MCU.
I am online and you can discuss with me. If found offline, just drop me an email.
Regards
Ch
