SmartMesh Mote(DC9003A) the LED can't work and send message betweeen motes

I buy a SmartMesh development board ----DC9007 ,those day I found the mote(DC9003A) led can't work which case me can't know if it work. I also found  the mote can not join the network automatic,after I take out the mote from the DC900A . I think if i start up some error command.Please give me some advice . The other  question is that i want to send messages between. I have link the  Tx and RX pin with the STM32F103 development board ,and I download the QSL-For-sm_clin-master program. How can i know the message has been sent and how can i monitor the data t or receive the data?
