recently i was working with msp 430 for simple tx/rx program and I am unable to send the packets and I am getting some errors in the last part (mrfi_transmit and &packets). Could anyone help? am new to this one. I am using IAR workbench

Hi sreenath,

I have some doubts on your thread.
* Are you using msp430 or eZ430-RF2500 USB dongle ?
* Are Imported whole project code into the workspace not a single c file?

Try this below Code of Simple tx and rx for eZ430-RF2500.
