From 62dbcbfc953a36202d96466563a8e71b8bd4ff65 Mon Sep 17 00:00:00 2001 From: "James A. Jerkins" Date: Sat, 30 Oct 2021 13:02:39 -0500 Subject: [PATCH 1/7] Connect and bond with a passkey This commit adds the following: Passkey pairing - passkey is displayed on watch Swipe down to clear passkey screen Connection encryption Connection bonding Automatic reconnects to a bonded peripheral Trusted device on Android Note that persisting the bond between reboots is NOT included in this commit. Therefore, rebooting the watch will cause reconnect failures. You must delete the bond from the phone to reconnect/pair. --- src/CMakeLists.txt | 2 + .../ble/BatteryInformationService.cpp | 2 +- src/components/ble/BleController.h | 11 +- src/components/ble/NimbleController.cpp | 106 +++++++++++++----- src/displayapp/Apps.h | 1 + src/displayapp/DisplayApp.cpp | 9 ++ src/displayapp/Messages.h | 1 + src/displayapp/screens/PassKey.cpp | 17 +++ src/displayapp/screens/PassKey.h | 20 ++++ .../porting/nimble/include/syscfg/syscfg.h | 16 +-- src/sdk_config.h | 2 +- src/systemtask/Messages.h | 1 + src/systemtask/SystemTask.cpp | 7 ++ 13 files changed, 154 insertions(+), 41 deletions(-) create mode 100644 src/displayapp/screens/PassKey.cpp create mode 100644 src/displayapp/screens/PassKey.h diff --git a/src/CMakeLists.txt b/src/CMakeLists.txt index e727b2b0..fecd09dd 100644 --- a/src/CMakeLists.txt +++ b/src/CMakeLists.txt @@ -154,6 +154,7 @@ set(NIMBLE_SRC libs/mynewt-nimble/nimble/controller/src/ble_ll_supp_cmd.c libs/mynewt-nimble/nimble/controller/src/ble_ll_hci_ev.c libs/mynewt-nimble/nimble/controller/src/ble_ll_rfmgmt.c + libs/mynewt-nimble/nimble/controller/src/ble_ll_resolv.c libs/mynewt-nimble/porting/nimble/src/os_cputime.c libs/mynewt-nimble/porting/nimble/src/os_cputime_pwr2.c libs/mynewt-nimble/porting/nimble/src/os_mbuf.c @@ -421,6 +422,7 @@ list(APPEND SOURCE_FILES displayapp/screens/BatteryInfo.cpp displayapp/screens/Steps.cpp displayapp/screens/Timer.cpp + displayapp/screens/PassKey.cpp displayapp/screens/Error.cpp displayapp/screens/Alarm.cpp displayapp/Colors.cpp diff --git a/src/components/ble/BatteryInformationService.cpp b/src/components/ble/BatteryInformationService.cpp index 9a3f86f5..82df7b15 100644 --- a/src/components/ble/BatteryInformationService.cpp +++ b/src/components/ble/BatteryInformationService.cpp @@ -17,7 +17,7 @@ BatteryInformationService::BatteryInformationService(Controllers::Battery& batte characteristicDefinition {{.uuid = &batteryLevelUuid.u, .access_cb = BatteryInformationServiceCallback, .arg = this, - .flags = BLE_GATT_CHR_F_READ | BLE_GATT_CHR_F_NOTIFY, + .flags = BLE_GATT_CHR_F_READ | BLE_GATT_CHR_F_READ_ENC | BLE_GATT_CHR_F_READ_AUTHEN | BLE_GATT_CHR_F_NOTIFY, .val_handle = &batteryLevelHandle}, {0}}, serviceDefinition { diff --git a/src/components/ble/BleController.h b/src/components/ble/BleController.h index 2cba26a9..72b87663 100644 --- a/src/components/ble/BleController.h +++ b/src/components/ble/BleController.h @@ -9,7 +9,7 @@ namespace Pinetime { public: using BleAddress = std::array; enum class FirmwareUpdateStates { Idle, Running, Validated, Error }; - enum class AddressTypes { Public, Random }; + enum class AddressTypes { Public, Random, RPA_Public, RPA_Random }; Ble() = default; bool IsConnected() const { @@ -48,6 +48,12 @@ namespace Pinetime { void AddressType(AddressTypes t) { addressType = t; } + void SetPairingKey(uint32_t k) { + pairingKey = k; + } + uint32_t GetPairingKey() const { + return pairingKey; + } private: bool isConnected = false; @@ -57,6 +63,7 @@ namespace Pinetime { FirmwareUpdateStates firmwareUpdateState = FirmwareUpdateStates::Idle; BleAddress address; AddressTypes addressType; + uint32_t pairingKey = 0; }; } -} \ No newline at end of file +} diff --git a/src/components/ble/NimbleController.cpp b/src/components/ble/NimbleController.cpp index 43a8b0d6..01901e0a 100644 --- a/src/components/ble/NimbleController.cpp +++ b/src/components/ble/NimbleController.cpp @@ -1,4 +1,6 @@ #include "components/ble/NimbleController.h" +#include + #include #define min // workaround: nimble's min/max macros conflict with libstdc++ #define max @@ -6,6 +8,7 @@ #include #include #include +#include #undef max #undef min #include @@ -45,16 +48,18 @@ NimbleController::NimbleController(Pinetime::System::SystemTask& systemTask, } void nimble_on_reset(int reason) { - NRF_LOG_INFO("Resetting state; reason=%d\n", reason); + NRF_LOG_INFO("Nimble lost sync, resetting state; reason=%d", reason); } void nimble_on_sync(void) { - int rc; + int rc; - rc = ble_hs_util_ensure_addr(0); - ASSERT(rc == 0); + NRF_LOG_INFO("Nimble is synced"); - nptr->StartAdvertising(); + rc = ble_hs_util_ensure_addr(0); + ASSERT(rc == 0); + + nptr->StartAdvertising(); } int GAPEventCallback(struct ble_gap_event* event, void* arg) { @@ -69,6 +74,7 @@ void NimbleController::Init() { nptr = this; ble_hs_cfg.reset_cb = nimble_on_reset; ble_hs_cfg.sync_cb = nimble_on_sync; + ble_hs_cfg.store_status_cb = ble_store_util_status_rr; ble_svc_gap_init(); ble_svc_gatt_init(); @@ -97,8 +103,22 @@ void NimbleController::Init() { Pinetime::Controllers::Ble::BleAddress address; rc = ble_hs_id_copy_addr(addrType, address.data(), nullptr); ASSERT(rc == 0); - bleController.AddressType((addrType == 0) ?
