sniffing of GATT protocol.

retag add tags

at starting Wireshark, it indicate "only advertising packets" wit check box in Message Box. then , I can see "LE LL" protocol on wireshark, but I can not see GATT. How do indicate GATT on wireSHark.? device:ADA-2269,nRF51822

Did you read https://www.adafruit.com/product/2269 and https://learn.adafruit.com/introducin... ? Was there enything that was unclear? Or at what step did you fail?

Thank you for your cooparation . I alredy read its URL. but it is need deep dive... I control the electric Outle throuh BLE by Android. it use GATT.

ADV_IND ;I confirmed it ADV_IND SCAN_REQ ; I confirmed it SACN_RSP ;I confirmed it CONNECT_REQ ; I cannot see. Is that because the Adv Hop are different? it is necessary setting another Adv Hop?
