How to use throughput routines to connect to any le bluetooth device

[lee123]

Hello, please help. I want to use nrf54L15 to connect to Bluetooth devices (Bluetooth headsets or other Bluetooth devices) and test the throughput between them. Is there any related routine?

I use the following routine to connect to GATT. Based on this routine, you can connect to any LE device, not necessarily the development board.The version is  2.9.0.

Hi Lee, 

Please give me the information on what you want to test first before going into modification. 

What do you want to achieve ? Why you want to change NUS to GATT (?)  Are you planning to connect to a 3rd party device that doesn't have NUS service ? 

Note that without a NUS (or proprietary ) service you can't do throughput test.

Yes, I plan to connect to a service device without nus. The solution I tested is to use GATT for message transmission, and then record the timestamp of the transmission to determine the current throughput. Similar to the following code.

Hi, 
Which exact characteristic you are planning to write to? 
Note that you can't write any amount of data to a characteristic without considering the max size allowed for it. 
I don't think you are going the right direction.

Thanks for your reply，The example you provided ：https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/samples/bluetooth/throughput/README.html. uses nus to test throughput, or  use GATT? What do you think is the correct direction to implement this function?Throughput test with third-party le Bluetooth devices
