Bluetooth data

Postby Zeriscope » Wed Jul 22, 2015 6:48 pm

Can the raw bluetooth data be captured and used without the use of special API or software? I am able to see a stream of BT data via the Android application BT Simple Terminal but it contains unusable info. We have done this with a different device and the raw data was displayed in numerical form and could be easily translated into a graph.

Thank you

Hi there,

The BITalino MCU can be controlled sending bytes directly, and encodes the raw data acquired from the ADC into an arrangement of bytes.

You can find the complete specification of the communication protocol and data frames on the MCU data sheet available at:
http://bitalino.com/datasheets/MCU_Block_Datasheet.pdf

We also have the firmware currently used by the device (which can also be useful for your assessment) available online at:
https://github.com/BITalinoWorld/firmware-bitalino

As such, you can most certainly bypass the APIs and high-level software applications, and communicate directly with the BITalino device.

Hope this information has been useful to help you achieve your goals. In case you have any further questions we'll be on this end to support.

Best regards,
The BITalino Team

What is the sampling rate for the sensors and can that be adjusted? Thank you.

Default sampling rate is 1000Hz and it can be changed by sending the command listed in Fig. 5 of the MCU data sheet:
