Christopher Collins updated MYNEWT-857: --------------------------------------- Summary: BLE Controller - incompatibility with iPhone 8 (and iPhone X?) (was: BLE Controller - incompatibility with iOS 11) This seems to be a link layer issue, so I don't believe the version of iOS is a factor. Lance, I have a few more questions if you don't mind: 1. Which iPhone model are you seeing this issue with? 2. Just to make sure - you weren't seeing this issue with older iPhones? 3. Did commenting out the call to {{ble_ll_ctrl_proc_start()}} help at all, or is the behavior the same? > BLE Controller - incompatibility with iPhone 8 (and iPhone X?) > -------------------------------------------------------------- > > Key: MYNEWT-857 > URL: https://issues.apache.org/jira/browse/MYNEWT-857 > Project: Mynewt > Issue Type: Task > Security Level: Public(Viewable by anyone) > Components: Nimble > Reporter: Christopher Collins > Fix For: v1.3 > > Attachments: ios2nimble-no-feat.pcap, ios2nimble.pcap, > nimble_ios_1033.btt, nimble_ios_1103.btt > > > Master: iPhone running iOS 11 > Slave: NimBLE device > The iPhone successfully establishes a connection to the NimBLE device, but > the CoreBluetooth {{didConnect()}} callback does not get called. A packet > trace (see attached {{ios2nimble.pcap}} file) shows that the iPhone never > initiates service discovery. > The problem seems to occur when the NimBLE controller initiates the Feature > Exchange Procedure immediately after connection establishment. The > {{LL_SLAVE_FEATURE_REQ}} PDU appears to cause a problem for the iOS device. > When I comment out the call to {{ble_ll_ctrl_proc_start()}} at the bottom of > {{ble_ll_conn_created()}}, the iOS device is able to connect and perform > service discovery, resulting in the CoreBluetooth callback being executed. > In the attached pcap file {{ios2nimble.pcap}}, the CONNECT_REQ is at packet > #6211. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
