NDEF_WriteText function read a temperature signal

[Schuyler]

I want to read the sensor signal with NDEF_WriteText function，How do you read a temperature signal instead of a temperature text?

NDEF_WriteText funtion is printf funtion，so what should I do to read signal？

Hi,@Rene Lenerve​ 

I found that the problem is caused by incorrect SPI initialization settings, which causes the data to be garbled.
