Bluetooth design, hardware and firmware

Предложение еще не подано

I could help you with the circuit and PCB design if you require but not the firmware I have designed quite a few bluetooth PCBs recently so I am very confident that I can get this correct first time If you are still interested please get back to ma and I will send some examples Best Regards Dave Lelievre

Hi Sir can help you , working with Bluetooth for more of 7 years working with lmx9838 very good chip ( national Texas ) and other cc25xx of texas and CC3000 last Texas chips, please see more modules Bluetooth in my portfolio. Design with Altium A14 CAD send full project and 3D model in Step Solid works and for easy view 3d in PDF format. Best Regards. Miky.

Hi, I am an Electrical Engineer practicing for last 8 years in an R&D Organization. I have designed a number of products ranging from RF & Microwave circuits to digital circuits. i have experience in designing filters, couplers, LNAs, Amplifiers, antennas, sweep generators, function generators, VCOs, NCO and many more in the frequency range of DC to 2 GHz. i use ADS, HFSS, OrCAD, Eagle PCB for the design and development of the above mentioned products. I have designed circuits for Filters, Couplers, LNA, Amplifiers, Antennas, Bluetooth, WiFi, GSM, GPS, Sweep Generators, Function Generators, VCOs, NCOs, DDS, 555 timers, AM Modulators, Microcontrollers, EEPROM, Flash, Accelerometers, USB, RTC, Strain Guages, Opto-couplers etc. My area of expertise include also PCB Schematic and Layout Design, Antenna Design, PCB Prototyping and testing, Programming using LabWindows, LabVIEW and MATLAB, etc. Looking forward to discuss in detail. Regards

Cheers, I have used in my past project BLE CC2540 from TI and v2.0 . That's my experience with this and also I've created a clone of this file.

Hello Sir. I can do what you need with quality and reliability. Please read more about me: I'm an Electronic Engineer, working with electronics circuits (digital, analog, mixed and of power) and embedded products with microcontrollers since 1996. My work as freelancer is my only work, so I work on the projects assigned to me full time. I already did a lot of Bluetooth designs, 2.4GHz trasceivers and Wi-Fi PCBs. For the PCB project I use Altium Designer 10 You will receive: - PCB project (the entire Altium project); - PCB file; - Schematic file; - Gerber files (for manufacturing); - PCB 3D modeling view. If needed, for the microcontroller I like to use the Microchip line, however I work with ALL microcontrollers brands. You will receive: - The IDE project; - Source files; - HEX file. I undestood all you need and I'm ready to start. I am ready to answer any question you may have. I hope you choose me. After hired we can stablish a full communication using email or Skype. Regards, Leonardo Takahata

I am an electronic engineer with 4 years of experience. I can work on your project. I have experience with rf and bl2.0 and ble 4.0 please contact me to discuss details

Dear Sir, I have experience in designing miniature circuits and programming microchips for Bluetooth Low Energy Applications. I have done many projects based on nRF51822. I would like to provide your my full effort for your successful project. Best Wishes.

Hi! I'm an experienced embedded systems engineer with over 8 years designing unique RF systems, including, but not limited to, RFID sensor tracking, telemetry acquisition and software-defined radio. I've worked with the CSR Bluetooth cores, including developing software that links against their proprietary onboard firmware (allowing me to skip the onboard microcontroller entirely). I'm familiar with the HID Bluetooth profiles and the overall stacks. I've worked on a few different RTOS systems in the past, and I have good understanding of the antenna and wiring requirements, Please feel free to contact me via Freelancer chat system to discuss my proposal further. Best Regards, Tomasz
