Again:

Go back to the original, unmodified example and confirm that works.

As suggested in your duplicate thread, Have you checked that the string conversion is actually working?

Yes - as also noted in the duplicate thread:

If you do not get any value, there is most likely some other issue. Check if the ble_nus_data_send function returns NRF_SUCCESS or some other error code.

What do you get over BLE? Note that sizeof(tempC) will return the number of bytes required to store a float (size of the type), which is 4, it will not return the actual length of the string.

Try something like this:

length1 = sprintf(str,"%f", tempC);
ble_nus_data_send(&m_nus,str,length1, m_conn_handle);

You should also check the error code returned from ble_nus_data_send().

Hi,

Could you explain exactly with the problem is? Are you not able to compile? Is the float value not showing correctly? Any other issue?

Did you try using sprintf with %f for the float parameter?

Best regards,
Jørgen
