How to increase Master BLE data rate

Sangram Jadhav

Hello Everyone,

We are current using a BLE Master to transmit a file to slave of approx. 400 KB, it takes about 7 mins to transfer this file.

Our objective is to reduce this time,

We used a sniffer to analyze this slow data rate and we found out that there only 20 bytes are transferred in a single packet

In the transmit window. Please suggest how to increase the data rate, our configuration is as follows:

Connection interval : 7.5ms

Slave Latency : 0

Supervisory timeout: 90 ms

We are in completion phase of our development, please suggest us a solution to increase the upload speed.

Regards

The overlapped processing feature introduced in the v1.4.0 release can help you improve throughput:

When using overlapped processing it can actually be beneficial to use a longer connection interval than 7.5ms (e.g. 20ms).
