Hello Giri, you helped me before by letting me know that MEP-SYS components are preprogrammed with low power version of Xmesh, which I didn't know.
My MEP-SYS is acting very strangely. Like you told me before, i tried to power-cycle the motes, but they kept that strange timing when sending data ( everything disrupted when i tried to change the Data Rate for All motes ). I couldn't make them return to original state. I tried to turn them ON, and OFF, but nothing changed. If you are interested to look at database here is the link to exported file:http://spreadsheets.google.com/pub?key=pwdlNhtbqezJtBaw98a8cdQ I left them turned OFF for 3-4 days, and now, when I turn them on again and start the moteview, nothing happens, just the xserve command prompt window opens, but no data is received. The MoteView is running for 3-4 hours but no data is received. do you have any idea how can I fix this problem? Also one of the things that's confusing me is that the base station readings are so strange, acctually I'm not sure, should it be any readings from the base station itself? Is there any way to return the motes in original state? Regards, Ognjen <http://spreadsheets.google.com/pub?key=pwdlNhtbqezJtBaw98a8cdQ> On 6/5/07, Giri Baleri <[EMAIL PROTECTED]> wrote:
Hello Ogenjen, Your settings seem correct. Make sure you are using \MoteView\xmesh\mica2\XMeshBase_433_lp.exe app from MoteView 1.2.B that is contained on the CD. The settings are Node ID = 0 GroupID = 125 Radio Band = 433 MHz Channel Number = CHANNEL_00 When I said power cycle, I meant tuning the nodes OFF and ON. If you want to change something in the Mote firmware, you should first make changes in the nesC/TinyOS code, recompile it and then reprogram the nodes. I hope that helps, Giri ------------------------------ *From:* ognjen popovic [mailto:[EMAIL PROTECTED] *Sent:* Tuesday, June 05, 2007 11:03 AM *To:* Giri Baleri *Subject:* Re: [Tinyos-help] MEP-SYS / MoteView 1.2 Problems Hello Giri, Settings I used for the Base Station are: Node ID=0, Group ID = 125 (0xfd) , RF band= 433 MHz, RF Channel = CHANNEL_00 ) I asked the xbow support about the RF channel. I read somewhere about LowPower mode cann't be used for reprogramming the motes, but I wasn't sure. I'm not really sure what does it mean power-cycle? If you could explain it little more? I tried to turn off all motes, and turn them on again, but nothing changed. It's not really most clear to me how could I change something with motes, if they don't support the commands?
