Products & Technology Shields
#1

Hi,

I bought the module bluetooth from grove, I transfer the slave exemple code in my arduino, connect my module bluetooth to “UART” of my shield grove.
But my android phone don’t see the module…

Thanks for future answers.

#2

when the code running, did you find the green and red led flash alternatly?

#3

No, just the blue led blink on my module.

#4

Then it maybe cause some problem when initializing. when initialize ok, the blue and red led will blink Alternately.

Could you share your code when initializing? :astonished:

#5

My code is the slave exemple code of the wiki page.
The module must to be in the “UART” of my shield grove,doesn’t it?

The Grove - Serial Bluetooth has used software serial but not UART, so you need plug it onto D6(digital 6 and digital 7) port of Base shield. Good luck.
