I have an Arduino that is successfully networked using the SparkFun WiFly shield.

I now want to add the SparkFun Temperature Sensor (TMP102) to this setup but apparently adding the Wireless to the Arduino and Temperature Sensor stops this from happening.

The output from the device is:

[WIFLY] Shield Terminal Routine
[WIFLY] Bridge initialized successfully!
[WIFLY] Rebooting
[WIFLY] Entering command mode.
[WIFLY] Set wlan to authorization level 0
[WIFLY] Set security phrase to 
[WIFLY] Set IP localport to 80
[WIFLY] Joining 'SensorNetwork'
........................................
[WIFLY] Associated!
[TEMP] Temperature read at -128 deg C

The temperature sensor is in a loop and therefore should continue sampling rather than just freezing. Removing the associated Wireless hardware and code leaves the sensor operating properly.

Can anyone suggest what is going wrong?

Code is online [here](http://www.csd.abdn.ac.uk/~cbaillie/arduino/WiFly_1/WiFly_1.pde)

Nobody can assist me?

Hi,

This might be one for the Arduino forums. They may be a little more familiar, and capable to help you on this one. Sorry we don’t have much to chime in on here.

It looks like the wifly is also using the sdl and sda … Pins 10, 11, 12 and 13 are connected to the wifly…

I2C SCL and SDA are analog pins 4 and 5. SPI uses digital pins (10), 11, 12 and 13.
