The proposed structure is consisted of three parts. A mini wifi board with 4MB flash based on ESP-8266EX. There is a schematic and board layout shown in the docs. Note: calculating the distance using RSSI depends on many factors such as the type of phone and how the user is taking the smartphone (in the pocket, in the hand, in a bagpack, etc). With progress slowly being made on turning the ESP8266 UART to WiFi module into something great, there is still the question of what the range is for the radio in this tiny IoT wonder. RSSI is an indication of the measurement for the strength of signal transmitted by an Access Point (AP) and is also the power level received by the receiver, therefore, it can be said that the stronger the signal, the higher the value of the RSSI [1]. RSSI(). D1 mini. In Thingspeak you need to set Field 2 for the Power field and if you want the RSSI the app uses Field 1. 2mm lens (called LS-40136) can focus at a very short distance making it a candidate for water meter reading applications. We will use a ESP8266 with RFM95 as a node and IBM 'Cloud' / Node Red as a back-end platform. Upload the “ RSSI_to_ThingSpeak. This does not include the Button 2/3 ability to reset to AP mode nor the “packet fix”. The ESP8266 must have 3. As you walk around with your mobile device, another beacon will eventually become the closest one and the app will detect this and switch to the information that associated with that beacon.
