Hi Mark

I'm sorry, but we're not too knowledgeable on embOS, as this is more of SEGGER's forte. If you want to use embOS and the RedBearLab I suggest you contact SEGGER or RedBearLab support.

If you just need to test the SPI of your nRF52811 I suggest you look at our SDK examples. We have examples for SPI, Flash_fds (Flash operations), temperature sensors, and more in SDK v.15.3.

Due to the summer holidays in Norway, our support team is understaffed this week, and delayed replies must be expected. Sorry for the inconvenience!

Best regards,

Simon

I'm able to conform the device responds with data when I send it the ReadBearLab command examples. The received data is not what I expect as I indicated. I need guidance on how to request an erase of the Flash page, or how to read something else, like the temperature sensor, by sending a sequence via spi_master_block_write().

You would have to ask RedBear - it's their code.

Might be simpler to just use an SDK example?

Note that SDK examples do come with pre-built hex - so you wouldn't necessarily have to go through building them yourself ...

couldn't you verify that by simply toggling the lines ... ?
