Change MTU on nRF Connect SDK

[martibalbi]

Hello,

I am developing a product that acts as a peripheral and sends a notification of more than 20 bytes (which is by default the BLE MTU). How can I config the MTU so that I can send at least 32 bytes when notifying? I am using nRF Connect SDK v1.5.1. I first noticed the problem because my peripheral was unable to send the notification because the central (a nRF52840 dk) didn't have enough buffer. 

I haven't been able to find clear information how how to config this.

Thanks in advance!

Hi, sorry for the late response. What you are looking for is called Data length extension. Can you please have a look at the kconfig BT_DATA_LEN_UPDATE. Thanks
