[mani]

Hi team,

Iam using sdk12.1.0(ble_app_beacon and ble_app_hrs_c) , i modified the advertising data and sending to other end.other end one scanner is receiving the data .but some times packets are missing.Is there any function to check error or giving acknowledge to the advertising data.

Hi mani,

Advertisement is unacknowledged (unreliable) communication channel so there is no ACK from scanner's side. If you want to transport data reliably you should use connection-based BLE link (or if you really don't want that you need to define custom data formats on top of ADV packets so it could work as CMD-RSP communication with acknowledgement/error detection mechanisms).

Cheers Jan
