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!

But the s120 has limitation of 1packet/connection, so max throughput with s120 will be 20b*1/0.0075 = 2666.(6) bytes per second. Only Master Emulator firmware lets to have more than one (six?) packet per connection, which gives ~16kBps (128kbps) throughput. But Your application probably won't use master emulator as central solution...

You are right, forgot that S120 only supports 1 packet/connection. MCP can have 6 packets per connection as it only supports one peripheral connection. if you are using IOS8.3 as central then it is 3 packets/connection. Stefan is making a report for throughput on various devices, we can wait until his report is out.
