OOB: Bluetooth device fails to connect to running examples (NRF52_DK) #138

Closed ghost closed 6 years ago

ghost commented 6 years ago

Trying to run example applications BLE_LED and BLE_LEDBlinker for 5.8 OOB testing using mbed-os-5.8.0-oob branch with suggested mbed-os branch https://github.com/ARMmbed/mbed-os/#d1ba1089a31ffab6b6a8887092b3d1fcc7c23b72

Connecting to the serial port of the device shows the correct output (BLE_LED in this case):

DEVICE MAC ADDRESS: e8:10:a0:6c:32:af

Connecting to the running device fails on NRF52_DK, however the same examples with the same configurations succeeds when running on an NRF51_DK.

Using the default commit used in the example works correctly: https://github.com/ARMmbed/mbed-os/#6ff720302e43c7a420232d134e786811cc7281a9

However, when changing to the commit suggested in the OOB form, the example fails to work: https://github.com/ARMmbed/mbed-os/#d1ba1089a31ffab6b6a8887092b3d1fcc7c23b72

Thanks for reporting @scartmell-arm.

Seems like phones that support it ask for a PHY upgrade that we're not handling properly. Fix is on its way.

Should be fixed by this pull request: Support for nRF52x BLE 4.2 and 5 events #6308; will update once it's merged.

Hello! Was it fixed @donatieng ? I am having the same problem here.
