1. Update concurrent scan of OneScreenM SR1.
2. Update the frequency band of the WIFI module.

Overview

OneScreenM SR1 is a Bluetooth low energy (BLE) to WiFi connectivity gateway without the uses of smartp hones or apps. The OneScreenM SR1 collects the data from iBeacon, Eddystone, BLE sensor and other BLE de vices, and then sends to the local server or remote cloud server by HTTP / MQTT/ TCP protocol over Wi- Fi /Ethernet. The subsequent version OneScreenM SR1 will also implement the connection with BLE devic es. This product is a science fiction with a color lamp ring on the top. It can be fixed by sticker or screw thread.

The meaning of the top LED Strip Lights status is as follows:

not connected to the server can be configured as a single color of red, yellow and white and adjust the brightness
Dynamic breathing lights| Indicates that the gateway is already connected to the server (Note: The gateway is in the dynamic breathing lights by default, it can step into the energy-saving mode on minute after extinction of lights, you also can set up bright mode in the configuration page if rich enough)
LED Strip Lights go out| Indicates that the gateway is not power or in energy- saving mode
Fast green flash(introduced since v2.0.0)|

1. Indicates that the U disk has been identified to gateway;
2. It will be displayed when the U disk is inserted for the first time or when the U disk is detected on the boot;
3. If you do not see the green flashing state within 15 seconds after inserting the U disk, it may be due to poor contact, please change another USB port and check whether the USB device is damaged.

Fast yellow flash(introduced since v2.0.0)|

1.  Indicates that the gateway is reading or writing data to U disk;
2. When the gateway reads and writes data to the U disk, it will display;
3. Do not force the U disk to be unplugged when the yellow flash is displayed. Such behavior may damage the file system of the U disk.
