nRF52840 best / simplest BLE service for data transfer

[Philip]

Hi All.

I have a DK52 project where a peripheral advertises and connects to a central nRF52840 ok. I based it on the multilink_central demo, so have the LED button service setup at the moment.

However it seems like a pretty complicated service just to basically send the state of the push button. I attempted to modify it so I can send big packets of data, but thought there must be a service better suited that I can modify instead?

What would be the best service in the examples to use / base a service on for the following;

1 - Send large arrays/packets of bytes from peripheral to central (max that can be sent in one message) to get best through put.

2 - Send some basic status information both ways.

Thanks

Phil

Hi Phil,

I hope this will help.  My device with the nRF51822 is receiving data from a smart phone and putting it into an array, and it is further processed internally with the Arm processor in the nRF51822.  There should be similar example code for the nRF52840.  Note though, I am only receiving BLE data, not transmitting.  Cheers, Brian
