I have a XBEE 3 Micro (XB3-24Z8CM Rev C) soldered on a custom PCB. The Xbee is connected to an Teensy 3.2. I can't connect to it via serial connection. I am using '+++' to get into AT mode, but get no answer.
I made the following connections:
- GND to Teensy GND
- VCC to Teensy 3v3
- DOUT to Teensy RX
- DIN to Teensy TX
Using an oscilloscope, i get the following signals on the pins:
1.GND) 0V 2.Vcc) +3v3 3.DOUT) 0V 4.DIN) my serial signal ('+++') 5) +3v3 6.RESET) +3v3 7->19) 0V 20.RSVD) +3v3 22->34) 0V
I'm especially surprised that I'm getting 0V on the ON-pin.
What am I doing wrong?
