InnocommSPI

Demo application to send sigfox messages using Innocomm eval board SN10-1X_EVB

Requirements

Code has been tested with Arduino MKR1000 board. This should work with Arduino UNO but you may need a level-shifter as the UNO board GPIOs output 5V and not 3V3.

The Innocomm shield is part of the EVK for the sigfox module SN10-1X: http://www.innocomm.com/en/product_inner.aspx?num=123 The sigfox module is based on NXP OL2385 chip. Code should be compatible with any sigfox verified board using OL2385.

Setup

Connect the shield to the Arduino pins as follows:

• Pins Arduino MKR1000:

  • SCLK: pin 9
  • SDO/MISO: pin 10
  • SDI/MOSI: pin 8
  • CS: pin 6
  • ACK: pin 7

• Pins Arduino UNO:

  • ***** NOTE: Arduino GPIOs supply 5V => Innocomm GPIOs expects a 3V3 so level-shifter may be required *****
  • SCLK: pin 13
  • SDO/MISO: pin 12
  • SDI/MOSI: pin 11
  • CS: pin 8
  • ACK: pin 9

Usage

3 functions have been defined in loop() to send payloads:

• sendPayload(payload, payloadSize) => send uplink payload only
• sendPayload(payload, payloadSize, downlinkFlag) => send payload and request ack
• sendBit() => send single bit

When powering-up the shield, you may need to push the reset button (or toggle reset pin of NXP2385 if using custom board) in order to put the chipset in a clear state
