Hello everyone!
Just have a look at this beautiful drawing. (Red: what has to be done. Black: Can it be done this way?)
I only have some rudimental experiences in microcontroller programming and none with bluetooth stuff.
For a part of my study I will need to wireless get data from 4 sensors.
After some research I came to the conclusion that the best way would be to use 4 of those chips from here: www.aliexpress.com/.../130096_1358212667.html
My sensors can be connected via I2C oder SPI. So that shouldn't be a problem. I already found the SDK for the nRF51822 and it looks promising so far.
What else will I need... Well the 4 modules have to be progammed/debugged somehow and send the data to some shared point... What is the cheapest+easiest way for this? The nRF51 Development Kit?
Sum up: 4 physically separated sensors who can communicate over I2C or SPI have to send wireless Data every (few) second(s) or so to a central data log point (another µC (nRF51-DK?) and/or Computer).
As far as my understanding goes, this should be possible with the PTRs using S110 Soft Device (peripheral) and the nrf51-dk using S120 (central)?
I found a guide nAN-36 Template Application: developer.nordicsemi.com/.../a00076.html ) which will hopefully enlightens me to code the peripheral side of the problem.
Is there such a guide/thing for the central part?
Most important part is to let the 4 PTRs transmit their sensor readings to the central unit. (Or the other way around if that's the way BLE is working.. still reading trough the nAN-36.pdf)
The peripherals will be in a fast circular motion (~120rounds per second).
Kind Regards
