I have tested the BNO055 against an actual Arduino, and it works.\r\n\r\nI've tried using pull-up resistors of various values, but without success.\r\n\r\nI've tried setting the Wire.setClock() to 100000, 200000, 300000, and 400000 as well as leaving it unset.  I've tried different pins for SCA/SCL without success.\r\n\r\nI don't have access to a logic analyzer or oscilloscope at the moment to dig into this at the protocol level, but I'm hoping someone here has advice to try.\r\n\r\nI did see #254, which seems related."},"comment":{"url":"https://api.github.com/repos/esp8266/Arduino/issues/comments/143784560","html_url":"https://github.com/esp8266/Arduino/issues/526#issuecomment-143784560","issue_url":"https://api.github.com/repos/esp8266/Arduino/issues/526","id":143784560,"user":{"login":"vicatcu","id":1018382,"avatar_url":"https://avatars.githubusercontent.com/u/1018382?v=3","gravatar_id":"","url":"https://api.github.com/users/vicatcu","html_url":"https://github.com/vicatcu","followers_url":"https://api.github.com/users/vicatcu/followers","following_url":"https://api.github.com/users/vicatcu/following{/other_user}","gists_url":"https://api.github.com/users/vicatcu/gists{/gist_id}","starred_url":"https://api.github.com/users/vicatcu/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/vicatcu/subscriptions","organizations_url":"https://api.github.com/users/vicatcu/orgs","repos_url":"https://api.github.com/users/vicatcu/repos","events_url":"https://api.github.com/users/vicatcu/events{/privacy}","received_events_url":"https://api.github.com/users/vicatcu/received_events","type":"User","site_admin":false},"created_at":"2015-09-28T15:45:52Z","updated_at":"2015-09-28T15:45:52Z","body":"FWIW, I'm pretty sure according to the datasheet the chip itself has hardware I2C.
