BLE-Link (SKU:TEL0073) transmitting high rate data
iofcehealth 2016-08-12 01:44:51 2871 Views6 Replies Hello, I have a BLE link connect to my arduino uno.
The arduino is also connected to a SparkFun Single Lead Heart Rate Monitor.
I want to transmit the ECG reading from arduino to my mobile phone through the BLE link.
How ever, I found that after several transmission (about 2 to 3 hundreds), some data will loss.
Is that normal for BLE link, as the data transmission rate is so high, which is about > 100Hz.
Or I need to some trick to achieve the high data transmission rate?
Or my BLE link is malfunctioned?
PS. If I connect my arduino to PC directly the data will not loss.
Thanks

I mean using a USB cable to directly connect arduino and PC, which means the data transmission is not through ble, but through the USB cable. iofcehealth

Have you ever tried to set the baud rate as 9600? Maybe the sensor data transmission rate is lower than BLE.
And what do you mean of "If I connect my arduino to PC directly the data will not loss." It means using USB to power the microcontroller or connect a external power supply or serial port communication? Wendy.Hu
