Hi there. In tutorial 6 the STS port is connected to a red LED, with a 220 Ohm current limit resistor. I have two questions for that setup, which I hope someone can clarify. ⋅  Why 220 Ohm? The docs says 370? Assuming a voltage drop of 2V across the led (pretty standard for red leds), and ...

Hi Francis I know this is a little late, but just wanted to point out that another reason the bluetooth module is used, may be because the NavSpark modules are all 3.3V LVTTL, and the Arduino is 5V.

You can improve signal by put antena on a iron ground pl...
