Sir, i had done sensor data read and monitor the PC via uart communication. but try to send RF communication is problem. sensor data read from floating variable, then convert float to string. Its working is well uart communication. but send rf communication using Fixed_LT_FIFO rf code is not send sir. If any solution for solve this problem. Please send soon.

    Hello Sivanathi,

    Yes, floating point numbers are challenging to manipulate efficiently using microcontrollers. Two recommendations would be to scale up your floating point number into an integer (e.g. 0.12345 into 0x3039) before sending it over RF communication or convert the floating point number into fixed point values using our Fixed Point Math Library for MSP (MSP-IQMATHLIB). Both would require a conversion on the other side but that should fix your issue.

    I'm sure other E2E users have had similar questions about doing this, so please search the forum for related threads.

    Regards,

    James
