Hi,
can some one tell me why this error come up? best regards Nils
How can i handle this error? Did i make a mistake by ATT config? Thank you for your answer
You did not make any mistake in the ATT Config, but you are not handling the BLE_GATTS_EVT_SYS_ATTR_MISSING event.
Do you use the bond manager in your application? This one should take care of the system attributes. If not you need to do as Ulirch mentioned.
