Let me explain how it works. First I need a device (in the terms of hardware AND software) and a server which holds services. However, I do not see an option in the app for configuring the GATT server as described. I have an iPhone running iOS 13.6. I am using a Rigado BMD-340 Dev Kit with NRF52840 for running the CTS example. I have the most updated version of the NRF app.

Let’s check the first one: UWP Console host. In general, UWP programs are desktop GUI applications, but with small tricks, console application can be developed also. Once you can read the data over L2CAP socket, everything makes more sense, for example, if your Android phone does gatt.discoverServices(), then the little program above will read (i.e. receive): 10 0100 ffff 0028 GATT server APIs add the ability to populate the actual server with attributes, but that is heavily implementation dependant and beyond the scope of this chapter. Exchange MTU This succinct two-packet procedure allows each ATT peer to let the other end know about the maximum transmission unit (MTU, or effectively maximum packet length) it can hold in its buffers and can therefore accept.

In order to make this demo we will use 2 ESP32s and Demo 26.

Battery Service (UUID=0x1801) Heart Rate (UUID=0x180D) So ESP32 will act as a GATT server and a GATT client (I use Raspbbery Pi3 with BLE or if your laptop is equipped with BLE you can use it). 2. Software - We will use LightBlue on iOS or on Android for testing or Bluez Gatttool for Raspberry Pi3 as a GATT client to connect to our ESP32 GATT server. 2.1 Bluez Gatttool for Raspberry Pi3 Application Example¶. Check bluetooth/bluedroid/ble folder in ESP-IDF examples, which contains the following demos and their tutorials: This is a GATT sever 27 Jun 2017 For example, a thermometer device will behave as a server when it exposes the temperature of its surrounding environment, the unit of 8 Mar 2021 In the example used in this topic, the Android app (running on an Android device) is the GATT client.
