Espressif Systems ESP32 was introduced in 2016, and one of the key differences between ESP8266 and ESP32 was that the latter supported Bluetooth 4.2.. But since then, the Bluetooth Special Interest Group (SIG) released Bluetooth 5.0 (2016) with higher speeds and longer range, and Bluetooth 5.1 (2019) adding direction finding for indoor positioning applications To get the screen on the LilyGO TTGO T-display ESP32 running need the TFT_eSPI library. This is a graphics and fonts library for ESP8266 and ESP32 processors with drivers for ILI9341, ILI9163, ST7735, S6D02A1, ILI9481, ILI9486, ILI9488, HX8357D and ST7789 based TFT displays that support SPI.Whilst you can install the library with the Library manager of Arduino I would advise you to install. micropython-master.zip; pyboard-master.zip; Firmware for various microcontroller ports and boards are built automatically on a daily basis and can be found in the pictured sections below. Alternatively, a list of all available firmware is here. Pyboard v1 and D-serie
