The final target is a SW program, that runs on our Analog Device BF504 microprocessor and controls a Microchip IS2023S module. At the end of this project, the IS2023S module should be able to establish a link to an Apple and/or Android Smartphone via BlueTooth protocol in order to exchange music and voice. We could already verify, that the IS2023S module controlled by a SW running on the microprocessor of an BM23 evaluation board is able to establish a BlueTooth link to a smartphone - and we have this microprocessor SW, which is written in "C". The first step in this project is to understand the available IS2023S control SW, to understand its structure and to compare it with the SW layers defined in the ISO 7 Layer model, which is probably referenced in the BlueTooth specifications. The second step is to strip down the received Microchip SW to our requirements and to remove all parts that have been implemented for the control of other Microchip devices and for the support of other BlueTooth protocols. The third step is to convert the remaining SW portions from the Microchip processor to our Analog Device BF504 microprocessor using the “C” and “Assembler” programming language. The last step is to debug the code on our BF504 microprocessor board with a connected Microchip IS2023S module. That means, you - have to understand the HW interface between the Microchip processor and the IS2023S module on the BM23 evaluation board - have to analyze a lot of IS2023S control code and BlueTooth specifications - have to design a layered SW architecture before starting the code conversion - have to balance your SW architecture with our existing SW architecture - have to port the useful IS2023S control code fragments - have to debug the ported SW - have to test the correct function in all “use cases” - have to write a usefull documentation explaining your SW architecture and implementation details - have to help me to integrate your SW in my system environment For this project, you need following skills: - very detailed experience with the development of BlueTooth stacks, - detailed experience with embedded SW design in programming language C, - experience with UART and SPI interface programming, - understanding of schematics for printed circuit boards.

Hello, I am electronic and communication engineer. I have worked over 6 years about embedded systems and this time many RF and Bluetooth module have been part of projects. I use C language for embedded projects but unfortunately I never use assembly except in my university time I know basicly assembly but expert on C language. We can talk all details over chat.

You need: software run on BF504 control IS2023S module to exchange music and voice over bluetooth with a Apple/Android smartphone. You have had already a C library that can control BM23 to establish bluetooth link. Your tentative working phases are: 1> Understand available IS2023S software 2> Optimise software by removing unnecessary part 3> Porting that software to BF504. Some parts need to be written in Assembler to optimise performance 4> Verify code with real hardware In order to finish work on time, you should ship a set of hardware when we start to test them here. Due to the complexity of your software stack, we should to discuss more to clarify how to finish your needs.
