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

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:
- returns limits (h: 0 and temp: -40) implying no communication
- hangs
- 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.

(here is the correct link to the video: )

I am having problems moving from xbee 1 ( to 2.5 ( 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
