Which GATT service is suitable for my application?

[mathan]

HI,

My application needs to send the data from PC(server) to Nrf52840(client) . The length and type of the data are 2758 bytes and char data type, actually data has been stored in the 2758 char array which are pixel values of the display. Which bluetooth SIG defined profile and service is compatible for our application? 

Regards,

Mathan Jeeva.

Hi,

Maybe this forum post is of intrest: https://devzone.nordicsemi.com/f/nordic-q-a/69848/is-it-possible-to-send-entire-array-over-ble 

You could use the Nordic UART service as mentioned in the above link. How you want to implement it on the PC side is up to you. If you want to send pixel values then maybe you want to display it on a screen.. so GFX lib might be of interest.

Regards,
Jonathan

Indeed - although that isn't a Bluetooth SIG defined profile:

mathan - have you looked at the list of Bluetooth SIG defined profiles? You should be able to find it on https://www.bluetooth.com/

yeah I have checked but I got the confusion which one is going to use

So which one(s) looked closest to your requirement?

If you say what your "confusion" is, people might be able to clarify it.

Or, as JONATHAN LL said, why not just use a proprietary profile - like NUS ?
