I´m working on parsing bytes from the Zigbee radio (NXP JN5168) connected directly on the Rpi3 serial port and I have some problem with split input using the SERIAL NODE configured as /dev/ttyAMA0, at some moments the split node doesn't make the message separation according to ETX character (0x03). Would you can see attached three messages whitout separation bellow:
When the same radio is connected through the USB-TTL Module, like CP2102, everything works very well.
I have make several serial node configuration possibilities, like without Optionally wait for a start character and timer values, but nothing worked.
Can someone help me?
