The ESP32-CAM module can be programmed with Arduino IDE. The ESP32-CAM module also has several GPIO pins to connect to external hardware. The important thing to note here is the "Port Range" and the "Device" or "IP address". In "Port Range" you should type 80-81.

Now, grab another ESP32 and upload the following sketch (the LoRa receiver sketch). This sketch listens for LoRa packets with the sync word you’ve defined and prints the content of the packets on the Serial Monitor, as well as the RSSI. The RSSI measures the relative received signal strength.

Sep 30, 2019 · For positioning, the so-called fingerprinting method is used. The strength of the Wi-Fi signals (received signal strength indication, RSSI) and the MAC address (media access control) are significant. For a client-based solution, the position is determined directly on a mobile device.

Apr 01, 2018 · Internally RSSI of all access points are obtained but only the RSSI in need is stored in ant_rssi[n]. Sweeping number “n” by the number of the antenna (here it is 3), RSSI for each antenna selection is obtained and the best antenna for connection link is determined. After best antenna selection, web-radio program running on ESP32-PICO-D4 ...

1RSSI (d0=1m) is the obtained RSSI reference value measured having transmitter (mobile device) at a distance d0 =1 meter from the ESP32 receiver station and "e" is the path loss exponent which is ... Hi Alec, I always recommend ESP32 for small packets sniffer but it also has some limitations like: sniffing one channel at a time or support only 2.4GHz band. I didn’t use CC2640+CC3100 chips but looks quite good. Probably on “clear” ARM it will be more challenging to create such packet sniffier than on ESP32. Physics sandbox 2ESP32-WROOM-32 is a powerful, generic Wi-Fi+BT+BLE MCU module that targets a wide variety of applications, ranging from low-power sensor ESP32 supports a data rate of up to 150 Mbps, and 20.5 dBm output power at the antenna to ensure the widest physical range. As such the chip does...A Bluetooth Serial library that allows you to use Bluetooth (not BLE) like a serial port. This way you can connect the ESP32 over Bluetooth to an Android app like the Serial Bluetooth Terminal and use it as a serial in/out interface. The library is not yet in the arduino-esp32 repository, but I grabbed a preview from copercini’s repo. Mitre saw guard
