How to print multiple float values in a raw

[Nikosant03]

Hi everyone,

I want to serial print three float values (x,y,z) from an IMU. I use the MACRO NRF_LOG_ERROR( "Float_Value:  " NRF_LOG_FLOAT_MARKER "\r\n", NRF_LOG_FLOAT(value));

When I print two values it works fine 

NRF_LOG_INFO("ACC X: " NRF_LOG_FLOAT_MARKER " , " "Y: " NRF_LOG_FLOAT_MARKER "\r", NRF_LOG_FLOAT(accRawData.x),NRF_LOG_FLOAT(accRawData.y)); 

But when I try to print three values it returns an error

NRF_LOG_INFO("ACC X: " NRF_LOG_FLOAT_MARKER " , " "Y: " NRF_LOG_FLOAT_MARKER " , " "Z: " NRF_LOG_FLOAT_MARKER "\r", NRF_LOG_FLOAT(accRawData.x),NRF_LOG_FLOAT(accRawData.y),NRF_LOG_FLOAT(accRawData.z));

maybe this MACRO cannot print more than two floats?

Is there any way of printing all three values in a row?

Thanks in advance

Nick

Hi,

The logger module supports a limited number of parameters. Please see this thread for details and workaround (using sprintf).

Hi Einar and thank you for your responce. 

You think it's fine to work with sprintf and then print the string with NRF_LOG_INFO for example?

Hi,

Yes, that should be fine.
