Hello~every friend

I am envolving in a project using the FSK module of SX1278 recently. It can communicate normally,however,the signal is so bad...The wave catched by frequency spectrograph is mess, I feel it’s in random dancing...so does the FEI measured by Fx port. Other boards recognized by radio frequency can operate normally.
I am doubting that if this phenonmence produced by the software ? So I checked my project, because what I made is linux drive with the packet mode,the interrupt input is dioO. Other DIO is vacant. The configuration BTW and register also is OK. Does the trouble caused by hardware? But I think the SX1278 is suitable here? This is the datasheet of SX1278 I used.( http://www.kynix.com/uploadfiles/pdf65976/SX1278IMLTRT.pdf
) Can anyone help me have a look?

Please give me some feasible suggestions! Appreciate it a lot![/url]
