I have a problem when trying 4FSK modulation using ADF7021, transmitted data is different with received data even though the modulation and demodulation configuration is same.
For my test, I am using 2 pair of EVAL-ADF7021DBJZ and EVAL-ADF70XXMBZ2 boards, also using ADF7021 Evaluation software. For checking the data, i am using oscilloscope and logic analyzer, and the data input is from STM32 microcontroller.
Here's my configuration.
Here's the data monitored by oscilloscope (upper tx, lower rx)
The transmitted data is different with received data. Previously i've tried using 2FSK modulation and succeed.
please help me, maybe my configuration is wrong or something.
