[Tinyos-help] TinyOS: MultiHop

[Pablo Gil Montaño]

Hi Hamdi,

in "TOS_MsgPtr pMsg" you must provide a pointer to a TOS_Msg field, which is defined in tinyos-1.x/tos/types/AM.h. In order to fill this TOS_Msg you mus previously call to 

command void* Send.getBuffer[uint8_t id](TOS_MsgPtr msg, uint16_t* length);

to get a pointer to the payload and fill the message. For instance, you can do a cast from the void* returned by previous command to the type of message you want to send, and then fill the message by using the pointer to your message type.

Regards,

Pablo Gil

Hello,

I'd like to use MultiHopEngine .. particularly the send and recieve  
interfaces.  I'm not exactly sure how to do this though:

command result_t Send.send[uint8_t id](TOS_MsgPtr pMsg, uint16_t PayloadLen)

what excatly needs to go in the TOS_MsgPtr for example?

Also, is this a good algorithm to use for MultiHop protocols? or is  
there a simple alternative.

Thanks!
