Notification Length Extension

[Hamzus]

Hi,

Using the nRF52832 device with the S132-v4.0.2 soft-device (s132_nrf52_4.0.2_softdevice)  (So customized that two nRF52832 devices with the same Soft-Device interact with each other).

I am sending a Notification from Server to Client with Data that i would like to Extend in order to send more Data (from 23 bytes to 30 bytes). I have understood that i could make an MTU exchange or a Data length extension (DLE) to make this happen. 

1.What is the difference between the two Options ?

2. Which Option is more suitable for me ?

3. How to implement the chosen Option ? (where should the code be placed? For example with the BLE_BAS service)

Thanks a lot for your Help.

Thank you very much Haakonsh !

Now i have better understood the difference between the two Options and i am opting for the MTU Exchange !
However, this answers the Question 1 and 2 but not the third one ! It will be really appreciated that you can help me with this One or maybe Assign someone who can .

Thanks a lot !
