Blynk.NCP low-level driver
A shared interface to the services provided by Blynk.NCP
Blynk.NCP is a solution that off-loads connectivity to a Network Co-Processor (NCP) while your application logic resides on the Primary MCU. This implies a dual-Microcontroller Unit (MCU) architecture.
When to use Blynk.NCP?
Using Blynk.NCP is recommended if one of these is true:
- You're building a new IoT product with specific requirements for the Primary MCU, and you're adding a separate connectivity module
- You are using Blynk for retrofitting your existing products
- You have included an **AT command**-based module, but you struggle to make it work right or to achieve your product goals
- You are looking for **ridiculously low** risks, integration efforts, and time to market, along with **improved reliability** of your products
Core Features
- **Blynk.Inject**: connect your devices easily using [**Blynk IoT App**](https://docs.blynk.io/en/downloads/blynk-apps-for-ios-and-android) ( Android, iOS) or [π Web Dashboard](https://blynk.cloud)
- `BLE`-assisted device provisioning for the best end-user experience
- `WiFiAP`-based provisioning for devices without BLE support
- **Network Manager**: WiFi (up to 16 saved networks), Ethernet, Cellular (depending on the hardware)
- Advanced network connection troubleshooting
- Secure **Blynk.Cloud** connection that provides simple API for:
- Data transfer with Virtual Pins, reporting Events, and accessing Metadata
- `Time`, `Timezone` and `Location` with an ability to track local time when the device is offline, including DST transitions
- **Blynk.Air** - automatic Over The Air firmware updates using Web Dashboard
- Both NCP and the Primary MCU firmware updates
- Direct firmware upgrade using iOS/Android App before device activation
Extra Features
Additional services provided by the Blynk.NCP:
- `β³ soon` Persistent automation scenarios - work even if the device is offline
- `β³ soon` Non-volatile storage for the [Preferences](https://github.com/vshymanskyy/Preferences) library
- `β
ready` NCP-assisted [fail-safe OTA updates](https://github.com/Blynk-Technologies/BlynkNcpDriver/blob/main/docs/Firmware%20Upgrade.md#ncp-assisted-fail-safe-ota-updates)
- `β
ready` Connectivity-related **device state indication** - requires a monochrome/RGB/addressable LED attached to the NCP
- `β
ready` **User button** (also used for configuration reset) - requires a momentary push button attached to the NCP
- `β
ready` **Factory testing** and provisioning
- `π€ later` Generic File System storage
- `π€ later` Generic UDP/TCP/TLS socket API
