Re: [Tinyos-help] Sending data to UART0 in tmote

2006-04-24 Thread Chris Pettus
You can also look at the example that I placed in CVS contrib (tinyos-1.x/contrib/SharedUSART/). This example switches between UART and SPI mode and allows you to transmit and receive bytes to a UART0 device over the radio. This is an example and has limitations so read the README file. Chris On

RE: [Tinyos-help] Rationale for 29 bytes payload

2006-04-24 Thread David Moss
Vinai, There were two motes used: One was Rx-only and the other was Tx-only. Nothing was competing for the radio. The throughput was at the application layer, using GenericComm. CRC's were checked, and the motes were sitting about 3 feet apart. The Tx mote would start sending a message, and

Hey all, In Surge_Reliable, the SurgeMsg has bytes for type, reading, parentaddr, and 4 bytes for battery and sequence number. I understand the type. But reading is never used, parentaddr is contained in the multihop header as Source Address?? And , why is there another sequence number??? and

[Tinyos-help] Sending a message to the Base Station from the PC

I found some previous postings having the same question but with no answer. How can I change the TOSBase code so when I send a packet from my PC to the MIB510 of the following format: 7E 42 FF FF 00 7d 0b 01 01 00 00 00 00 00 00 00 00 00 69 b0 7E 42packet without achknowledgments

I'm a little unclear on the concept here... I'm guessing that turn the LED ON means that you are trying to send a message through TOSBase to a re-Mote that is running whatever program that knows to flash LEDs for that message. I forget, is that the SimpleCmd demo app? How are you sending the
