BreathUp: PCB, AES, LMIC and LoRa

Hi!

As already explained by Benjamin and Alexandre, we received our PCB. Sadly, they contain some mistakes that will need to be patched and the LoRa part is quite compromised because of that… But anyway, we will do our best during the end of the week to patched them and you will be able to find an update in next Sunday’s post.

I also worked with Alexandre to set up our ChibiOs project, including: configuring the board, the clocks, creating a basic test program…

Eventually, I worked on LMIC and AES. I concluded that we cannot use LMIC’s AES function for the Bluetooth communications and we will therefore create an other one.

For the end of the week I want to work on the patch of the PCB, the basic development on the PCB (LEDs, PWM, UART, shell…) and on LMIC implementation on RFM95W chip that we might use in our PCB patch.

Have a nice end of the week,

Xavier Chapron
