Hi,xbee S1 and S1 pro can be used in one network?

are they compatible with each other? can I used both of the two kinds module in one digimesh network?I have updated the S1 firmware and build up a digimesh network.

Yes, the S1 and S1Pro are compatible with each other provide they use the same channel and firmware. IE both need to be using either 802.15.4 firmware or Digi Mesh 2.4 firmware.
