I have a board with the following components
Rfduino BLE chip (RFD22301)
u-Blox CAM M8Q GPS
MPU 9250 (9-axis accel/gyro/magnetometer)
Micron N25Q00AA (1 GB flash memory)
A switch, resistors, etc.
I would like to gather data from the IMU and the GPS, store in flash, and transmit in comma separated format (if possible, I'm not sure how the new BLE protocols work). I have a barebones firmware written up with most IMU functionality and some GPS. Looking for someone to help code the rest of the functionality. Will compensate of course. Let me know if you're interested and I can give you more details.
Thanks!

Dear Friend, Hi there
We like to inform you that we have good experience in embedded programming and hardware. We can help you in this project as per your satisfaction. So as we see you want to extract data from MPU and GPS store on flash then transmit via Rfduino BLE in CSV format. It seems quite doable and we are open to discuss it further.
Thanks for the time.
Consider us, Have a good day !
Regards
Gaurav Sharma

Dear client,
I am very interesting on project. I had completed a similar project, an Android IMU App, which connected to an IMU device through blue teeth. I designed the core algorithm of IMU.
I want to know the scenario of your application.
Hope we have a chance to cooperate.
Best regards,
Xiao Long
hello,
I am very interested in IMU and GPS, and have serious projects developed with them, so it would be great if we cooperate and do some great job. I have experience in software architecture and avr based boards programing.
There are several sketch example for Bluetooth BLE connection manager out there so you could use it for free. It is similar and as easy as what serial sketch code you commonly use. Simply set the advertisement data and name of your device, and then it will be used for sending any data to connected device. That's pretty easy.
Your project includes :
-Integrate sensors. (To cancel noise, subtract acceleration).
-Remove noise. (Kalman filter)
-Integrate IMU measurement into GPS.
The data communication between Arduino and the different components uses the SPI since it is possible to connect different sensors in just one line.
I have used the Indoor positioning system in my project "RobotStreaming" a robot controlled over the Internet and I have a good experience in programming over Arduino and STM32F4.
