Hi,
Is there a way to access the analog inputs other than having to enter the command mode? I need to interface a 3 axis gyro and a 3 axis accelerometer to the module using the voltage divider bias resistors. Please help.

Thanks

I got this module and I’m trying to build a temperature sensor monitor.Everything has done and it’s time to comunicate this module with my notebook.Firstly,can you tell me the program that communicates the module with a notebook?I read the datasheet and i should use ”teraterm pro” ,it’s written there…

Yes, I know the specs of the device, but I am wondering how to connect an NTC resistor taking into account the Wifly constrains, I mean:

- 3.3 V on device power source.

- 0-400 mV range (I want to cover the 0 to 80 or 100 ºC range).

- Never pass over 1.2 V limit for the sensor pin, to avoid damage (ok, if 400 mV are 100 ºC i don’t have to take care about it).

Could you give me some clues please?

The WiFly-GSX has 8 analog interface inputs that can be sampled using the show q command. The
hardware specifications on the analog input is:
Input voltage range: 0 – 400mV.
Resolution: 14 bits = 12uV.
Accuracy: uncalibrated: 5%, calibrated using precision voltage or resistor measurement: 0.01%
See the WiFly-GSX (RN-131G) data sheet for more details.

I have this module and I trying to figure out which could be the best way to use the sensors option, what do you mean with •NTC temperature option (if temperature sensor connected to module – otherwise sensor 7) and Spare sensor reading? which could be a possible NTC configuration? I am a software developer but a newie in electronics.

Could you help me?
