Excellent suggestion! I now have 20 working. So the strategy is:

- test 3-4 at a time
- get their ids
- add ids to an array of known devices

thanks!

Hi,

I am inclined to suspect a software bug perhaps in the search function. I have a bunch of sensors on a board for testing and am able to get 5 sensors reading reliably, but when I add 2-3 more sometimes it works and sometimes I get into loop mode where it never gets to the last address.

It doesn't make sense to me that a network would need to be split with just 5 sensors on a board.

- using latest code, parasite power....

any thoughts would be greatly appreciated

I am having problems getting the SHT15 to communicate with a pro mini 5v. All the code works with the mini but not the pro mini. I have tried a few examples using code off the web:

http://www.flatline.net/journal/2008/04/11/arduino-reading-the-sht15-temperaturehumidity-sensor/
- returns limits (h: 0 and temp: -40) implying no communication

http://ragingreality.blogspot.com/2008/01/ardunio-and-sht15.html
- hangs

http://www.glacialwanderer.com/hobbyrobotics/?p=5
- returns ACK error 1

Has anyone had similar difficulties? solutions?

thanks, don

thanks for the info... although i am guessing that i am in trouble if i don't have access to a windows computer (i have a mac) to do the firmware transfers.

I am having problems moving from xbee 1 (http://www.sparkfun.com/commerce/product_info.php?products_id=8665) to 2.5 (http://www.sparkfun.com/commerce/product_info.php?products_id=8695). It was my understanding that they are pin compatible and should work just the same for simple serial transmission.

see an example video:

any suggestions would be much appreciated
