I am currently trying to add BLE GATT services to an ESP32 which is part of a BLE mesh network. I am currently using NimBLE as the stack in an ESP-IDF project.
The confusing part is because the GATT server initialization is handled internally in the code when initializing the BLE MESH node. Hence, I do not have the handle to the GATT server to add or modify the services and characteristics it is advertising.
Can somebody point me in the right direction please?
I'm trying to communicate with a Bluetooth Optical Probe using a SPP (serial port) that is attached to a smart meter. I have seen that using the Gurux software will be a good idea. However, they do not offer native support for Bluetooth communication (other than in the Python example) and their mobile support is only for Android-Java. Has anyone managed to create an instance of IGXMedia within Gurux for Bluetooth? The Gurux BTSerial class uses System.IO.Ports.SerialPort which is only available on Windows, where I am trying to use Cross-Platform C#.
The latest bluez supports ble mesh interfaces (APIs). But, I don't know exactly what is the sequence that I should call by using these interfaces as a provisioner.
First, I can start to call UnprovisionedScan() and CreateNetwork and AddNode... and some authentication and provisioning interfaces. Could you guide me to the correct method calling sequence?
I have traied meny examples to connect Zebra IMZ320 Blutooth using Iphone on Xamarin Cross-Platform
I followed CoreBluetooth Namespace
enter link description here
and also using Plugin.BLE
but I couldnt connect my device eny one has success experience in connect Bluetooth printer using Xamarin cross platform ios
CoreBluetooth.framework is for Bluetooth Low-Energy:
Communicate with Bluetooth 4.0 low-energy devices.
The Core Bluetooth framework provides the classes needed for your apps
to communicate with devices that are equipped with Bluetooth low
energy wireless technology.
According to the specifications of the Zebra IMZ320, the communication mode are:
Secure Bluetooth 2.0, 802.11a/b/g/n (optional) or USB (client)
connectivity; Wi-Fi®-certified connectivity
That is not Bluetooth Low-Energy (which has been introduced in Bluetooth 4.0). You won't be able to find the printer with a Bluetooth Low-Energy scan, because the behavior, logic and implementation (protocols, norms, GATT, Peripheral/Service/Characteristic) are totally different.
Also, the description page of the Zebra IMZ320 gives a link (FAQ - Creating & Registering An IOS App) to how develop apps for it.
You need to use ExternalAccessory.framework for it.
If your app communicates with a Zebra product via Bluetooth using the
External Accessory Framework, and you plan to distribute the app via
the App Store or Volume Purchase Program Store, then you must register
the app with Zebra.
This page is general (and not specific to that printer). But according to the specs, it's not Bluetooth Low-Energy compliant (while others products might be, that's why there is a paragraph talking about CoreBluetooth in it).
That's normal behavior (using ExternalAccessory vs CoreBluetooth framework), because each one of them has a specific meaning and use.
Conclusion:
Use ExternalAccessory.framework, it is also available on Xamarin.
I have two peaces of nRFO24L01, one of them is connected to arduino and second one is connected to RPi. For communication between them I used this library https://github.com/tmrh20/RF24 and this communication working very good. Now I want to have web services on RPi which have to be able to communicate with arduino through the nRF24L01. The best option should be some java web services on tomcat server but I can't manage to find some kind of wrapper which will provide me easily connection between c++ code from mentioned library and web services. Is there any solution for this?
For communication between arduino and RPi I used getting started example from mentioned library from github.
See the RF24Ethernet lib from the same guy:
