Exactly, I know that I'm able to call txBytes from my own code but I can't seem to get it to work because of the error about a connection from within NoCRCPacket explained below: I've searched the documents for areas regarding "calling a command from another module" but no luck. Aside from this being my 14th hour working on this project, could you please at least direct me to the proper documentation that would explicitly explain the syntax to make this command call. Thanks! I'm starting to run out of ideas.
In component `NoCRCPacket': /opt/MoteWorks/tos/platform/micaz/NoCRCPacket.nc: In function `receiveTask': /opt/MoteWorks/tos/platform/micaz/NoCRCPacket.nc:306: Receive.receive not connected -----Original Message----- From: Michael Schippling [mailto:[EMAIL PROTECTED] Sent: Monday, March 17, 2008 9:27 PM To: Mark Tsang Cc: [email protected] Subject: Re: [Tinyos-help] Utilizing a command from another module, I may have spoken out of turn but the 'provides' block in the T1 file is: > module NoCRCPacket { > provides { > interface StdControl as Control; > interface BareSendMsg as Send; > interface ReceiveMsg as Receive; > interface SendVarLenPacket; > > command result_t txBytes(uint8_t *bytes, uint8_t numBytes); > /* Effects: start sending 'numBytes' bytes from 'bytes' > */ > } > uses { > interface ByteComm; > interface StdControl as ByteControl; > interface Leds; > } > } Which seems to indicate that you could "call txBytes(...)" from your code, but I'm resistant to becoming familiar with that special syntax. If that doesn't work, then close study of the nesc doc is indicated. MS Mark Tsang wrote: > But NoCRCPacket doesn't have an interface. It looks to be a standalone > module.
