Hi,

The NRF52840  Bluetooth  will act as central  and the other  controller Bluetooth will act as peripheral. The other controller bluetooth has one 128 bit base uuid and 4 128 bit characteristic uuid .Here my doubt is how to add 128 bit base uuid and 4 different  128 bit characteristic uuid  as i am new to this controller .can you plz tell me how to add all the characteristic uuid.

Thanks for the reply.

I have read the link which you have sent.I need to add the service and characteristics on the central side.But these are from peripheral side.

can you plz give me suggestion for this.

Exactly the same procedure to adding services/characteristics on the peripheral and central. There is no dependency between the GATT database (services/characteristics) and GAP role (peripheral/central).
