Connections of module bluetooth RN4678
« on: November 12, 2018, 06:58:50 pm »
Hi everybody

i'm using this module, i be able to connect with my smartphone but there isn't the bits over the TX pin.
My schemartic is in the image.

Now i'm not using the PIC uC so for Wake up pin i'm using a button, as explained in datasheet, and for SW BTN a button with two positions.

P2_0 --> Vcc
P2_4 --> Vcc
EAN --> GND

this to use module in normal mode

In the schematic I added the CTS pin put to ground through a 1k resistance.

With LEDs D101 e D102 I can stable, through a table in the datasheet, the state, and in my case are in the state "Not connected to peer device".

I hope you can help me

Thank you
