Forum Post: could not receive data through UART

Hi All,

I am using zstack-1.4.3-1.2.1 and cc2431 and SRF04EB. i loaded serial app code on to 2 modules running on 2 SRF04EB's.

The coordinator is starting a network and router is joining that network. but they are not receiving data from UART. I tried to debug one of the module. the "rxCB" call back function is not being called.

How to perform data transfer from UART? Pl. help me.

Thanks in advance.

Regards,

Mahesh
