interface 2420Packet not found Tinyos

Question

every time i tried to get the Rssi value from a received packet i get this erreur

interface 2420Packet not found 

my code is

message_localization_t msg=(message_localization_t *) Packet->data;
int_8 Rssi_Value=call CC240Packet.getRssi(msg);

And i tried to do this:

unit_16 Rssi_Value=Packet->strangh;

but when i tried to complicate the module file i get this erreur please help me!!

Answer 1

Try with CC2420Packet instead of 2420Packet when using interface.

Answer 2

it didn't work with me either but i finally found the solution in order to get the value of Rssi from the received packet i wrote the following code:

in the receive part of:

 event message_t* Receive.receive(message_t* pck,uint_8 len){ 
 unit_8 Rssi_value =pck->metadata[1]//for Rssi value check message_t specification
