Streaming frequency

Hello,

I just started working with the SmartBond DA14583 and I was wondering if it is possible to set the frequency of the accelerometer and gyroscope to 100Hz while streaming, and if it is possible to stream via Bluetooth at 100 Hz.

I read on the documentation that the default performance while streaming is 12.5 Hz for the accelerometer and 10 Hz for the gyroscope.

Thanks in advance

Alejandra

Hi gomezago,

Hi gomezago,

I need some clarifications regarding your questions. Could you please let me know which document are you meaning? Be aware that in the IoT Sensors application we support up to 100Hz accelerometer's data rate. The available maximum data rate for the application is 100Hz, the sensor can support up to 1600Hz, but the sensor fusion implementation can't handle that fast update rate so there isn't any implementation for higher data rate. Same for the gyro as well the sensor can support up to 3200Hz data rate but not the application. Your question is regarding the DA14583 or regarding the sensors that you are using?

Please have a look at the DA14583 IoT Sensor reference design

Hi! I meant this:

Hi! I meant this:

"Performance for sensor fusion and streaming

Settings: 12.5 Hz Acc; 25 Hz Gyro, 10 Hz Magneto, 0.5 Hz Environmental (pressure, temperature, humidity)
Connected : < 1.3 mA
Advertising: < 110 uA
Power save: < 11 uA"

Maybe I missunderstood what that meant.

My question was about the DA14583. But from what I understand now it supports a maximum data rate of 100 Hz, right?

Thanks,

Alejandra

Hi gomezago,

Hi gomezago,

陀螺和加速度计可以传输@100Hz但the magnetometer can transmit @10Hz. DA14583 can transmit this data over ble packets. Please check the 12.3 Bit Rate Performance paragraph of theUM-B-063 User Manual DA14583 IoT sensor development kit.

Thanks, PM_Dialog
