Setting and exchanging MTU size over GATT

[Sachin]

Hi,

 We are implementing a file transfer between nRF52810 using nRF Connect SDK 1.9.1 and Android devices.

I am not able to identify exact config parameters to set the max supported MTU size. And also call back which can indicate the set MTU size post negotiation.

Please do help me with the same.

Thanks in advance

Hi

prj.conf

CONFIG_BT_L2CAP_TX_MTU=276
CONFIG_BT_BUF_ACL_RX_SIZE=276
CONFIG_MAIN_STACK_SIZE=8192

Also you should do MTU exchange procedure from peripheral or central side
