First setup
| Wifi ssid | ESP_0 |
| Wifi pass | configesp |
| IP | 192.168.4.1 |
Emergency reset
During power up, if TX & RX lines are tied together.
Device is sending two bytes (115200 speed): 0xAA 0x55 and after 1ms checks if two the sames bytes are received, and resets device to factory settings.
Delayed reset
When failed connection tries reach 30, system is performing delayed reset (after 60 seconds).
Function ESP.reset() is used.
