Hi pal,

You need to decompose the data for sending, and reorganize in the base station.

I have asked the similar question, for your reference.

I am trying to send multiple sensor data under a profile to a base station via BLE.
The current sensor data size is 256KB in total. I want to send this data to the system for analysis.

Can I achieve that ?
If 256KB is too much, then how much is the maximum size I can transfer?

OK.

Hi,

What do you mean by "stream 256KB of data at a go"? Could you elaborate in more detail? What issue do you see? A sniffer log might help to know what happened in the air.

[quote user=""]what is the maximum MTU size that i can put in thr prj.conf file?[/quote]

The max MTU size for nRF53 is 498.
