Hi dear Engineers! How to read 128uuid of characteristic ? I try to use sd_ble_gattc_characteristics_discover(..) then wait BLE_GATTC_EVT_CHAR_DISC_RSP. But uuid always 0x0000 according to the Photo:

I founf the answer. To discover the random 16 UUID of unknown characteristic I have to use

1. sd_ble_uuid_vs_add() if known 128 UUID vendor part

2. sd_ble_gattc_attr_info_discover() with Unknown vendor UUID, if S132 + nRF52 uses

Thanks you.
