I am using an Xbee 900HP in API mode using UART. I am transmitting a command to it using my micro and expecting a response. Based on my Oscilloscope waveforms the data i expect back is being received however it it followed shortly after by a slow curved drop in the UART line. Has anyone else experience this?

I have attached pictures of the packet received as well as the "curved drop" that follows for your reference.

  • \$\begingroup\$ Nothing that I have been able to find (have read it back to front multiple times). I have found that placing a 10K pull up resistor on the RX line of my Micro has eliminated the "drop" but hasn't exactly answered my questions. \$\endgroup\$ – user3095420 Oct 25 '15 at 4:47
