* 20190916 - initial: support for Master mode, Pin and SSP * 20190916 - initial: Add example app for Master mode * 20190916 - initial: Force another build * 20190916 - connect would use resolved address as preference and remove now redundant _remote_address * 20190916 - rework set/reset/default pin logic * 20190916 - cleanup: remove static vars, add/use constants, fix typos * 20190916 - fix build issues and implement geoup events for status verification. * 20190916 - remove extra lines,misc * 20190916 - rework ESP_BT_GAP_DISC_RES_EVT, added SPP_DISCONNECTED bit for disconnect event. + timeout for disconnect() * 20190916 - Small log change to improve log sequencing * 20190916 - remove static from local vars * 20190916 - Limited scope and duration for the scan, log device address during scan in info mode as it is very difficult to find out sometimes. Fixed get_name_from_eir() not resetting the name when called. * 20190916 - break property for loop during scan when name matches. * 20190916 - misc * 20190916 - SPP_DISCONNECT state updates * 20190916 - formatting, remove some strange syntax from initiator code * 20190916 - Add comments to the example about connect(...) usage and timeouts * 20190916 - fix disconnect() without timeout * 20190916 - Add example comment to view BT address and name during connect(name) * 20190916 - wording in example comments * 20190916 - rework connect() and disconnect() methods to help with concurrency and more authoritative status returned back to caller. Automatic disconnect in connect() methods * 20190916 - optimize code * 20190916 - optimize code - more * 20190916 - add timeout for pin set * 20190916 - change scan mode to ESP_BT_SCAN_MODE_CONNECTABLE_DISCOVERABLE * 20190916 - update example code slightly * 20190916 - increase READY_TIMEOUT to 10 secs * 20190916 - typo in example and move waitForConnect() to static area * 20190916 - update example comments * 20190916 - update example comments * 20190916 - update example comments * 20190916 - add new example to remove paired devices from ESP32 * 20190916 - correct typo in example * 20190916 - update example comment, add remove_bond_device() method for convenience. * 20190916 - reword example comment. * 20190916 - rename remove_bond_device() * 20190916 - rename removePairedDevice() to unpairDevice() * 20190916 - code review changes * 20190916 - fix return value in setup() od example
