Discovery bypass

[Fabien Comte]

Hello,

I do connections between 2 nrf51 with a known and static services. Is that possible to bypass the discovery to access a characteristics (i know all characteristics) ?

Thank you

Yes, you can use the handle directly if you know that they will not change.

Use the sd_ble_gattc_write function, and give the known handle.

Another solution if you know the UUID, but not the handle, is to perform a sd_ble_gattc_char_value_by_uuid_read call to extract the handle of the UUID. This is much faster than performing a full service discovery procedur.

Edit: In order to find the static handles you can use Master Control Panel to perform service discovery.
