Is Bluetooth LE a good choice for low rate streaming?

[Lakerno]

I am designing a ECG monitor device. The data rate is less than 50kbps. I was planning to use BLE for the device design. But I read some documents that say BT classic is a better choice for streaming. In my case, BLE can support the datarate I need, so using BLE than BT Classic will save me some power.

Does anyone here developed a BT device for streaming applications? Did you use BLE or BT classic? why?

Thank you!

For what it's worth, there is existing work using BLE for ECG. You might want to review them to get some insights into the pros/cons:

TI has an approach: www.ti.com/.../ecg_bluetooth_low_energy.shtml

There are a lot of academic discussions. All of the following require IEEE access, but many libraries can get articles for free (I've shortened the titles; use the links): BLE ECG monitoring system: ieeexplore.ieee.org/.../login.jsp ; ECG data with the patch-type BLE sensor: ieeexplore.ieee.org/.../login.jsp ; 1V 5mA multimode IEEE 802.15.6/BLE WBAN for biotelemetry applications: ieeexplore.ieee.org/.../articleDetails.jsp ; Evaluation of BLE for Continuous Data Transmission from a Wearable ECG: ieeexplore.ieee.org/.../articleDetails.jsp
