Other Parts Discussed in Thread: CC2650, CC2650STK
Hi, I'd like to know what is the maximum possible rate/frequency for acceleration and gyro measurements of the sensor. Can it take measurements up to 100Hz? Thanks for a response in advance, Mathias

Hi Mathias,
From the CC2650 perspective, over Bluetooth low energy, this is fully possible. The limitation lies in the external sensors on the board.
This is the movement sensor used on the eval board:

Hi Joakim,
thanks so much for the quick response!
I think I have to elaborate a bit (Excuse myself for the longer explanation, as I'm relatively new to this and I couldn't quite get from the data sheet whether it would solve my issue):
My aim is to build a fitness app. So I want to focus on the app building part, rather than on hardware. So, what I'm looking for is a sensor (that I can for demo purposes make a "wearable") which can send information wirelessly to a mobile device. As I understand it this sensor can do that and TI also enables with its cloud platform to visualise the data rather easily. Thus, I'm interested whether I can use this sensor "as-is" and have accelerometer and gyro data displayed at >= 100Hz? - I hope I could clarify my request. My aim is to find a device, where I can take the hard ware and focus solely on the software part of it.
Thanks again,
Mathias
