RE: [Tinyos-help] CRC Calculation

For TosBase, crc is necessary. If you want to disable it, you can modify TosBase by using other component, for example, HPLUARTC will enable you to receive UART data by byte without crc check.

Hi,

I don't know about disabling the CRC, but as far as the bytes that are considered in the calculation: the CRC calc includes all bytes in the message except for the start and stop bytes (0x7E). Also, remember to calculate the CRC BEFORE you replace reserved bytes in the message.

Good luck,

Matt

Hi,

I want to send custom messages to TOSbase. What bytes does the CRC consider for its calculation? Is there any way to disable it?

Regards,

Prasanna.
