WisBlock Environmental Sensor RAK1906 Example compilation errors

WisBlock
#1

Good night,

Recently I bought some WisBlock board and Sensors. I mount a board with the sensors RAK1906 and RAK1903. I compiled the examples for RAK1903 without problems, but when I tried to compile the example for RAK1906 for BOSH BME680 I am receiving a lot of compilation errors (pasted below):
Could you help me?

Erro compilando para a placa WisBlock Core RAK4631 Board

#2

Bosch BSEC library changed in November 2020.
In order to get it compiled for WisBlock you need to change one line in the RAK BSP.

Please locate the file boards.txt inside the RAK BSP. On Windows the path is:
C:\Users\>USERNAME<\AppData\Local\Arduino15\packages\raknrf\hardware\nrf52\0.21.1
>USERNAME< should be replaced with your username.

Open boards.txt with a text editor (notepad or similar, NOT WORD) and look for this line:
WisCoreRAK4631Board.build.mcu=cortex-m4 -mfpu=fpv4-sp-d16 -mfloat-abi=hard
it should be line 38.
Change the line to:
WisCoreRAK4631Board.build.mcu=cortex-m4
and save the file. Close ArduinoIDE, open it again and try to compile the example again.

I am sorry for the inconvenience. We are in the process to update the BSP and will release a new version soon.

Hi Bernd,

Thank you by your support.

I am working on it now.

I will send the News as soon as possible.

Well much better now!

I still have some “warnings”. Could you help me to fix them?

#5

Can you send me the warnings?

Some warnings are caused by libraries and cannot be resolved by us.

Thank you by your support.
