package received change its original form

hello everyone,

i did a test using two xbee in radio mode to transfer the package. in fact the software tried to send a serial of characters one by one, and seperated each other by space. but when we received package, some space is lost and certain of characters group together. i tried to modify the parameter RO to 0, but it didn’t change anything, if i tried RO with a value greater than 10, the package lost all of the space inter-character. does anyone have idea about this kind of thing?i use broadcast mode, with firmware XB24 XBEE 802.15.4 version 10E6 with a baudrate of 38400.

PS: i wish i could attach some images but i don’t have the permission. :stuck_out_tongue:
