WaveOfHoney - a lorawan beehive sensor

Compilation

Clone this repository, then :

mbed deploy
mbed config root .
# set the desired compiler
mbed toolchain GCC_ARM
# set the desired board
mbed target NUCLEO_L073RZ
# set-up the compiler path if needed
mbed config -G GCC_ARM_PATH /opt/gcc-arm-none-eabi-7-2017-q4-major/bin

Bootstrap mode

This mode is used to initialize a mbed NVStore on the flash and store board-specific parameters. To compile the bootstrap binary you have to set "mode-bootstrap" to true into mbed_app.json and set lorawan EUIs and key.

mbed compile --profile profiles/release.json

Then you can use flash the board and start it. You can check the serial console to see

Production mode

Just reset "mode-boostrap" to false and compile it (you can delete BUILD folder from previous compilation) :

mbed compile --profile profiles/release.json

In this mode, lorawan parameters are ignored (because the program get it from the flash) but leave it as-is because they are used to determine the stored size ot the euis and key.

Notes

Tested boards

• MTB_RAK811
• NUCLEO_L073RZ + SX1272MB2xAS

use STLink from a Nucleo board with the RAK811 board

From STlink CN4 Connector to RAK811 "shortest" connector (pin 1 at the same side of antenna connectors)

2 -> 3 (CLK)
3 -> 1 (GND)
4 -> 4 (DATA)
5 -> 2 (RST)

rewire STLink on a cutted Nucleo board

From STlink CN4 Connector to Nucleo CN7

2 -> 15 (CLK)
3 -> 19,20,22 (GND)
4 -> 13 (DATA)
5 -> 14 (RST)

From STLink CN3 Connector to Nucleo CN7 (stdio through USB)

rx -> 1 (USART4_TX)
tx -> 2 (USART4_RX)
