Data delay on XBEE S2 802.15.4 Network

0 votes

I had a configured Xbee network (802.15.4) with 7 modules (being one the coordinator) and all others as end devices (all modules connected to Arduinos). Applied to a Wireless sensor network, however I am having some issues with a delay between the messages, all messages are fully send/receive but sometimes the xbee network delay on delivery the messages (holding it for a few aleatory seconds between 1s and 7s that I don`t know why!). My modules send continuously messages that some times it arrive separately (it is right, is what should happening) and sometimes they came together (caused by the delay). I`m monitoring the messages (strings) with several terminal commands, that is how I discovery this issue.
Has some one any idea of why is it happening?

I think if you use default settings on all the modules the performance will be better.
Also check the Sleep parameters on the end devices.
