Hey guys

I have 5 SensorTag and I want steaming motion data to one computer via BLE port. can someone enlighten me?

Is it okay to use python to get data?

I never had streaming data experience. So should I get those data then save it to buffer or stack then print on screen or save it in an array? any examples that I should learn first???

I need SensorTag working at 100hz sampling rate for motion data. is that possible via one USB bluetooth dongle?

You can use sensortag app to stream and store the data. The data will be saved as csv file, which you can send it to yourself and analyze from there.

Hey Christin

thanks for your suggestion. But I want receive 5 sensortag's data simultaneously. It looks like phone app can't do such work.

Then you can modify your sensortag to output data through UART, then you will be able to have as many as you want.
The wikipage below includs how to add serial communication to any CC2640/CC2650 devices
processors.wiki.ti.com/.../CC2640_Serial_Communication

Another way will be using Btool with CC2540 dongle, however, this can only connect to max 3 device at a time.

I didn't use UART. I used python with pexpect and bluez on ubuntu to commucation with SENSortag. it looks okay for sending data. but I need sync all the sensortags data on same time line.
