DA14583 data rate

We will try the accelerometer and gyroscope datarate the ascent to 200 hz, but in the end, the collected data, both sensor only 150 hz, or less.Could you tell me whether this is a bluetooth transmission speed limits the datarate?In addition, whether can change new DA1468x support accelerometer gyroscope gather enough under the condition of 200 hz datarate data?thank you

Hello, please give more specific parameters.

Hello, please give more specific parameters.

The following to make some assumptions:

Accelerometer and gyroscope samples is 6 bytes at a time, a second: 6 * 200 = 1200 bytes;16 bit sampling depth, it is 2400 bytes

If the data receiver is mobile phone, the influence of the bluetooth transmission speed limit is that cell phones.With 58 x series DSPS engineering, iOS can to 3 ~ 4 kbytes/s, is to be able to meet your requirements of data transmission

We will sensor combination set for gyro

We will sensor combination set for gyro + acce, frequency are set to 200 hz, the ios mobile taking these two sensor data.
Acce range is set to 16 g, gyro is set to 2000 deg/s.Because of big workload resulting in a decline in performance?

hello

hello

Don't know what is your environment?Is to use the Dialog of the sensor iOT?
