What are the initial settings for BlueGiga WT32 Breakout?

Right now I am currently working with the BlueGiga WT32 Breakout Chip. I have searched and searched but I cannot seem to find what the initial settings for this chip need to be. If anyone knows what they are would you please respond to this.

Hi,

Can you be more specific what initial settings are you concerned with.

Serial Comms are set 115200 8, n, 1

I am trying to get a simple HyperTerminal connection to a WT32, packaged as the breakout board (http://www.sparkfun.com/commerce/produc … ts_id=8952), so I can send a few initial commands to the chip which should allow me to pair it with a device.

I am not using an Arduino board, this is just the breakout board and a MAX232 wired together. 3.3V is going to the WT32, 5V to the MAX232.

I’ve got the following pin connections on a breadboard:

WT32 RTS → MAX232 Pin 9 (R2OUT)

WT32 CTS → MAX232 Pin 10 (T2IN)

WT32 TX0 → MAX232 Pin 11 (T1IN)

WT32 RXI → MAX232 Pin 12 (R1OUT)

MAX232 Pin 14 (T1OUT) → RS232 3 TX

MAX232 Pin 13 (R1IN) → RS232 2 RX

MAX232 Pin 7 (T2OUT) → RS232 Pin 7 RTS

MAX232 Pin 8 (R2IN) → RS232 Pin 8 CTS

So it looks like, when you abstract the MAX232 out:

WT32 RTS → RS232 CTS

WT32 CTS → RS232 RTS

WT32 TX0 → RS232 TX

WT32 RXI → RS232 RX

The BTEN pin is active.

What am I doing wrong?

You definitely need to swap your Tx and Rx connections at the “RS232” end…

And you should be using a MAX3232 / ICL3232 for 3.3V work…

A schematic would be easier to follow.

Did you get my hint from the other thread?

Hi Blank 142,

I have sent you a datasheet .pdf document to the email shown in your profile. The datasheet shows the RS232 connections used on the WT32 evaluation kit.
