NRF_LOG_INFO does not show float number

[djqtsg]

I use the following code:

NRF_LOG_RAW_INFO("\t (%f %f %f)\r\n", fgx, fgy, fgz);

I get

(f f f)

What is missing here?

Hi,

You need to use NRF_LOG_FLOAT_MARKER and NRF_LOG_FLOAT() to print floats, as described in the documentation:

NRF_LOG_INFO("My float number" NRF_LOG_FLOAT_MARKER "\r\n", NRF_LOG_FLOAT(f)))

Best regards,

It looks like this no longer works properly in the latest SDK (nRF5_SDK_13.0.0_04a0bfd.zip).

NRF_LOG_INFO("My float number: " NRF_LOG_FLOAT_MARKER "\r\n", NRF_LOG_FLOAT(15.32f));

now gives the output

APP:INFO:My float number: 15.2d

It looks like the interpretation of %02d has changed, and that it now interprets %0 as an empty string and outputs a literal "2d".
