[jira] [Commented] (MYNEWT-642) Eddystone UID format is incorrect

    [ https://issues.apache.org/jira/browse/MYNEWT-642?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15884598#comment-15884598 ] 

Simon Ratner commented on MYNEWT-642:
-------------------------------------

Additionally, i think `BLE_EDDYSTONE_MAX_SVC_DATA_LEN` is one off, should be 22.

> The format of the eddystone beacon, as generated by `ble_eddystone_set_adv_data_uid`, is incorrect.
> According to https://github.com/google/eddystone/tree/master/eddystone-uid, the UID frame starts with 0x00, followed by calibrated rssi at 0m, followed by the 16 byte uid, and finally 2 zero bytes to pad to the full 31 bytes.
> By comparison, `ble_eddystone_set_adv_data_url` seems to be doing the right thing.
