Hi,

 

I am using the FXTH87 with the NO_LF_PWU_WAKEUP mode with the PWU_PERIOD to 5 seconds (I tried about any time). The problem is every time a PWU occures and the frame is send, the frame is corrupted. If I add several send commands like so :

vfnSendCompleteRFFrame();
vfnSendCompleteRFFrame();
vfnSendCompleteRFFrame();
vfnSendCompleteRFFrame();
vfnSendCompleteRFFrame();
instead of sending just one frame in at PWU, I always get the first frame corrupted and the following frame which have the right CRC. It is like if while it is sending the first frame he is calibrating. Because I want to consume least current, I want to send just one frame each time. How to correct this to have the fist frame already correct?
