This instructables show how to use ESP32 to make wireless BLE signal scanner, all scanned data will send to the HTTP server via WiFi. ESP32 is a series of low cost, low power system on a chip microcontrollers with integrated Wi-Fi and dual-mode Bluetooth. The ESP32 series employs a Tensilica Xtensa LX6 microprocessor in both dual-core and single-core variations and includes in-built antenna switches, RF balun, power amplifier, low-noise receive amplifier, filters, and power management modules. ESP32 LoRa Communication using Arduino IDE The IoT industries introduced lots of technologies, but none of them was ideal for IoT devices, as they needed to transmit information to a long distance without using much power until the LoRa technology was introduced. LoRa Technology can perform very-long range transmission with low power consumption. ESP32 is a low-cost, ultra-low-power, single or dual-core SoCs from Espressif Systems with integrated WiFi and dual-mode BT module. The processor core is based on the Tensilica Xtensa LX6 32-bit Controller Processor Core. Features of ESP32 [ TOC] The key features of ESP32 are: Espressif ESP32 BLE¶.

GND - GND VCC - 3.3v/Vin SDA - D2(GPIO4) SCL - D1 (GPIO 5) Due to the power requirements of the LCD, it may not be bright enough when connected to the 3.3v pin of the ESP32. If that is the case, connect the VCC pin of the LCD to the Vin Pin of the ESP32 so it can draw power directly from the connected power source. With ESP32, you may not want to use another microcontroller. ESP32 has Xtensa Dual-core 32-bit LX6 microprocessors that run up to 600 DMIPS. The ESP32 will run on the breakout boards and modules from 160 MHz up to 240 MHz . this is a great speed for anything which requires a microcontroller with different connectivity options. Bei der I2C-Kommunikation verfügt jeder Slave am Bus über eine eigene Adresse, mit der der ESP32 mit jedem Gerät kommunizieren kann. Die I2C-Adresse finden man im Datenblatt der Komponente. Wenn es jedoch schwierig ist, dies herauszufinden kann mit dem folgenden I2C-Scanner die I2C-Adresse herausgefunden werden: ESP32 WROVER (OV2640) SKU: U017 Description M5Camera is a development board for image recognition. It features an ESP32(4M Flash + 520K RAM + 4M psram) chip and 2-Megapixel carmera(OV2640).M5Camera offers plenty of storage, with an extra 4 Mbyte PSRAM. It also supports image transmission via Wi-Fi and debuging through USB Type-C port.

Thakur In this tutorial we are making ESP32 as both Station and Access point and web server . We have seen how to connect to WiFi Router and make web server in previous post . i am working on the ESP32 chip and am trying to get the all avaliable information from advertising. For this purpose I use the nRF connect app by NORDIC with prepare advertiser . I scan for the device and successfully only read the complete name but i want to extract all the information from advertising. And, as it is mentioned in the documentation, on the ESP32, the MAC address is random and will be generated when the BLE interface is activated. So you can use the BLE Scanner application to find the device MAC address as shown in Fig. 3. A Thermal camera connection board along with software for running it on a ESP32. At the moment the software supports sending thermal images to a tcp server. Thermal images can be viewed via the webapp and different cameras can be connected. Future planning is to add native mobile support, so the camera can be connected directly to a phone.
