Functions Xbee Shield provide in integration with mdot

[Colin z.]

Hi all,

To send data from Arduino with Lora, I tried mdot with Arduino + xBee shield + mdot. The AT command works as expected according to the documentation.

However, I’m wondering why not connecting the RX and TX from Arduino and mdot (RX<->TX) directly with wire, instead of using xbee shield?
The shield also costs some extra money to buy.

Then I tested with Arduino and mdot by wiring their RX with TX to see if I could get the same result. For example (Serial.write(AT)), I should get (“OK” from mdot). Unfortunately, there was no output from mdot.

Before doing more debug, just want to know if this is fundamentally wrong? Can I still use AT command in this mode? Is xbee shield a must during the integration?

Any input is much appreciated!

Does the Mdot have power to it? Have you tried other pins to see if they produce an out put? What XBee shield are you using?
