Oct 04, 2017 · As a first project with my new ESP32 module with OLED display I chose to build OLED clock. I thought I’ll just find some existing code, upload it and it’s done. There are a few such projects for ESP8266 in NodeMCU. In the previous posts you learned how to use the esp32 chip to receive and parse the advertising packets transmitted by BLE peripherals. As a practical example, I developed a program to detect the presence of a particular iBeacon and activate an output accordingly. Bluetooth Low Energy (BLE) is a slightly different protocol than the traditional Bluetooth we might find in things like Bluetooth audio, for example. Instead of constantly streaming data, BLE "servers" (like the ESP32 reading sensor data) can "notify" clients (like your smartphone) periodically to send them bits of data.

BLE example demonstrates how WiFi BLE Click acts as iBeacon - with the help of the right commands we've created a beacon which allows us to scan it using the app called Beacon scanner. Only some of the commands that WiFi BLE click supports were used in the example; for the rest of the available commands check the documentation

iOS + BLE (Part 2, ESP32) Some time ago I wrote a bit about iOS and BLE using the RedBear iOS library from this page ( read my previous article here ). I was using an ESP32 for a recent project and didn't want to make any modifications to my iOS app so I needed to tweak the ESP32 example BLE UART sketch a little to work with my iOS stuff. We will program the ESP32 to act as a BLE client and constantly keep scanning for BLE devices; if we find the fitness band in range we will try connecting to it and if the connection is successful we can trigger a light bulb by toggling one of the GPIO pin on the ESP32. The method is reliable because each BLE server (fitness band) will have a ...
