How to send data with high speed

[MrFine]

Hi I was use example ble_app_uart with SDK 12.3.0 and nrf51802 for a data transport, after BLE connection, the example need uart receive more than 20 or "\r\n" ,the data will send to the peer device; I want to know how to send the data without need "\r\n" or large than 20, and also have a high speed to transmit data ? did you had similar demo?

Thanks!

You can modify ble_app_aurt easily to trigger different "end of frame" condition then \r\n and similar you can play with the "frame" size of 20B (chaining them in some way if you need to send more).

Thanks for your reply,Maybe I didn't make that clear; I want use the example like a real serial port line; I dont want any end of frame to trigger; so for a high-efficient transpotr if uart receive 20 or more , I can send it immediately, buf if less than 20 , I dont know when to send them.do you have a good solution for this?

Well define your condition and fire the transport anytime you need. It can be e.g. at 20B or lower if some timer expires (100ms/1s/10s). In the end it will be you who will need to write it into the FW anyway, nothing will save you from that work I'm afraid...
