BLE instructions are old #93

Closed johnnyman727 closed 8 years ago

They should no longer have a section about obtaining root and running hciconfig

zshannon commented 8 years ago

This section still needs to be present, and PR#94 should be reverted. I just lost a lot of time debugging the ble module not powering on, and running the hciconfig hci0 up fixed it instantly.

@zshannon sorry to hear you had some difficulties. I wonder if perhaps the hotplug functionality is not available on some dongles? Can you paste a link to more info on your BLE dongle?

zshannon commented 8 years ago

@johnnyman727 I'm using this one from Amazon (I think it's the recommended one)

zshannon commented 8 years ago

@johnnyman727 after several more hours of debugging, the issue seems to have been bluetoothd competing to control the bluetooth connections. When I removed it from startup on the Tessel, bluetooth connections started working as expected (in bleno; using hotplugging control). Any clue where I should create a new issue about this?

@zshannon if you could open an issue with details on how to reproduce on openwrt-tessel, that would be perfect. Thanks!
