GainSpan WIFI Breakout Board power up?

Wireless & IoT

Hi All;

I just bought one of these rather cool modules, WRL-10505, and was pleased to note 4 contacts at the bottom of the board, VCC/GND, TX/RX… cool!

So I hooked up PRT-00114 (Reg. 3.3V PS) to the VCC/GND pins, and got nuthin. Shouldn’t one of the LEDs on the Breakout show a power indication?

The docs indicate that this module can be powered up 3 different ways, Always ON, Standby Enable, DeepSleep Enable. etc…

How are the VCC/GND pins wired up on this?

Thanks!

Did you look at the SparkFun schematic?

not till just a moment ago… too busy digging thru the docs. :oops:

It appears to be setup as AlwaysOn, so that answers one question.

But not the second. Should I have an LED on powerup?

Since these are GPIO outputs, and also designated as testpoints, then I’m not really sure. GPIO leads me to believe that, when I take the bit HI, I have an LED turn on.

But since it’s a testpoint, that seems to indicate that I should be able to read something there on powerup.

nothing in the docs yet, still digging.

I had the same question, but when I hooked up some serial to the Tx and Rx pins at the bottom, I saw some communication so it must have been powered on. There were never any leds indicating power was on, or startup was complete or anything like that.

My problem now is that my serial communication is jibberish. I am using a program called RealTerm and have my settings to that of the default gainspan board (9600,8,n,1) and when I send the “AT\r” command, I do not get a proper response. I should be getting either an “OK” or “0” but I get something that starts with a P and is a couple of extra characters long. It looks like my settings are wrong, but there are endless options for settings.

Do I have to reset the board back to factory defaults?

Is it possible to set the board back to factory defaults?

Any idea what’s going on?
