+# Use Lilygo T-Display to show ThermoBeacon measurements
+
+![Photo of the display in action](photo.jpg)
+
+
+T-Display is an inexpensive dev module based on ESP32 LX6 with a 135x240
+TFT LCD display. It has built-in radio (WiFi & Bluetooth, incl. BLE) that
+can be powered from 3.3 or 5 V, and programmed over USB using Arduino
+tools and libraries.
+
+This project turns it into an autonomous temperature and humidity display
+that collects data from up to two ThermoBeacon BLE sensors. BLE scanner
+is passive, it only listens to the advertisement frames sent by the sensors.
+If more than two sensors are present, measurements from the first two, are
+displayed, based on the RSSI value (that means, presumably, the two sensos
+in the closest proximity to the display module). No configuration should be
+necessary.
+
+One of the buttons (GPIO 35) toggles between graphic display of battery
+charge and signal strength, and MAC address (last three octets).
+
+Depnedencies: `ArduinoBLE` library and `Bodmer/TFT_eSPI`.
