 If it cannot connect to the Blynk server in 30 seconds, it will switch to `Configuration Mode`. You will see your built-in LED turned ON. In `Configuration Mode`, it starts an access point called `ESP_xxxxxx`. Connect to it using password `MyESP_xxxxxx` .

+### Releases v1.0.4
+
+***Why this version***
+
+I'm really fed-up with the unfriendly, confusing and cryptic DHCP hostnames such as `ESP_XXXXXX`, `espressif` using ChipID. Thanks to an issue opened in library ESP_WiFiManager, I decided to add this option to have built-in, yet configurable DHCP hostname to these libraries.
+
+Now you can easily specify and have the friendly, identifiable, RFC-952-conformed DHP hostnames associated with your boards, such as `SmartFarm-1`, `Irrigation`, `Master-Controller`, etc. You'll be happier to have a look at your WiFi Router DHCP list.
