Arduino-u-blox-NINA-B1

u-blox NINA-B1 Arduino example + SHT31 temperature and humidity + Bluetooth BLE

How to build PlatformIO based project

1. Install PlatformIO Core
2. Download development platform with examples
3. Extract ZIP archive
4. Run these commands:

# Change directory to example
> cd platform-nordicnrf52/examples/Arduino-u-blox-NINA-B1

# Build project
> platformio run

# Upload firmware
> platformio run --target upload

# Build specific environment
> platformio run -e nina_b1

# Upload firmware for the specific environment
> platformio run -e nina_b1 --target upload

# Clean build files
> platformio run --target clean

Why?

This example tries to implement some key functions and key PIN atributes in order to get you started with using Arduino and the NRF52832 BLE board u-blox NINA-B1.

Timer functionas are implemented intead of delay() and the PINs have been re-mapped on the #define section

Bluetooth iOS and Android app

You can download the sample Bluetooth low energy app - BLE App straight from u-blox wesite: https://www.u-blox.com/en/product/bluetooth-ios-and-android-app

fatal error: ble_gatts.h: No such file or directory

The arduino-nRF5x core REQUIRES a SoftDevice in order to successfully use this library. Please see Flashing a SoftDevice.

On PlatformIO and when using this example you don't need to do anything special as the build_flags = -DNRF52_S132 has already been included on platform.ini file.

SoftDevices contain the BLE stack and housekeeping, and must be downloaded once before a sketch using BLE can be loaded. The SD consumes ~5k of Ram + some extra based on actual BLE configuration.

• SoftDevice S132 v2.0.1 supports nRF52 in peripheral and central role. It is 112k in size.
