Hi everyone, I’m buy new WiFly module http://www.sparkfun.com/products/10004

Now I’m connected:

  1. pin 12 and pin 13 → Rx,Tx UART (3.3 TTL level).

  2. pin 19 and pin 18 to ground and 36-44 to ground too.

  3. pin 20 and pin 21 to +3.3V DC power

  4. pin 26, 27, 28, 29 → LED indicator

  5. pin 24 it’s jamper, and connected to +3.3V DC power (for adhoc mode)

But my WiFly module doesn’t work right, I can’t find new network access point from my laptop, computer or Nokia 5800, and any LED’s don’t flash or ligth ON :?:

Then I’m connect my module to computer (UART-USB) (FT232RL), and open TeraTerm terminal and connect him to virtual com port COM10, I see cycle responde from WiFly module:

What is my problem? Please help me.

Oh my. You decided to leave a little work for us then… :shock:

Okay:

  1. Looks like your powering the WiFly module from 5V. Not good.

  2. The FTDI FT232RL IC can only supply 50ma on it’s regulated 3.3v output. The WiFly module needs up to 212ma when transmitting, insufficient current may cause it to reset.

Answer those and we may be able to continue.

I’m use 3.3V DC from USB 5V (see on picture)

Image doesn’t work but hey-ho, how about putting some decoupling capacitors on that regulator you have there…

АААААААААААААААА!!! Module is working!! :lol: :lol:

The case was in feeble regulator 3,3 V, which is seen only 100 mA current, and the WiFly module need to 240 mA from it and continuously reset in the hope that it will be enough power! When I powered from power suppla. Immediately LED’s blinked, signaling that the WiFly module works. :idea:

After which the network has a new access point to which I have successfully connect, and my Nokia 5800 too! :lol:

Mind your language!

You certainly showed Sparkfun who was boss by not buying that uber-convenient breakout break…

Your this

should become a classic for SFE!

I profit in this topic to ask if I can power my Arduino UNO with a USB cable or do I have to use a regular power cable ?

:shock:
