How to improve master-slave throughput between two nrf52832

[Skyliu]

download code from：github.com/.../nRF5-ble-timesync-demo

A Device:    nRF5-ble-timesync-demo-master\nRF5_SDK_14.2.0_17b948a\examples\ble_central\ble_app_uart_c

B Device:    nRF5-ble-timesync-demo-master\nRF5_SDK_14.2.0_17b948a\examples\ble_peripheral\ble_app_uart

I test data transmission between devices A and B.  B device to A device can only transmit normally below 5 k bits/s.  

If the transmission rate  above 5 k bits/s，the device A can't receive any data. But I expect the data rate could reach 300 k bits/s.

How to improve master-slave throughput？

thank you！

Hi

The time sync demo is not suited for high data rate transmissions like this. Might I suggest you use the "regular" SDK examples for ble_app_uart instead?

Best regards,
