Hi all, I'm using two zigbit amp with tinyos based on the latest eth code found on the old tinyos-contrib cvs. Everything seems to work fine (I receive and send packets even in LPL) except for one test that I'm used to perform on new platforms: I burned the Null application (including the ActiveMessageC component as it should be done for IRIS platforms) and measured the current draw of the node. Based on the datasheet, the expected current draw should be lower than 6uA but in my case I'm not able to reach values below 160uA. I forced MCUSleep to return ATM128_POWER_DOWN as lowest state and disabled the amplifier pulling low the PC1 port of the cpu but nothing changed. I noticed that the CPS pin of the SE2413l (the front-end) stays high which avoids the fron-end to go in sleep mode and I think that this is the main reason of the unexpected power consumption. Unfortunately Atmel does not give the schematics of the ZigBit Amp and I have not been able to pull this pin low (nor I've been able to understand how bitcloud manages it). Does anybody have worked on it and could help me?
Ugo p.s. Janos: I've seen an old post where you say that you've worked on that module, have you experienced the same issue? -- Ugo Maria Colesanti Dipartimento di Ingegneria Informatica, Automatica e Gestionale "Antonio Ruberti" Sapienza Universita' di Roma Via Ariosto 25, I floor, room B112 00185, Rome http://wiserver.dis.uniroma1.it/cms/index.php/contacts/13-postdoc/4-ugo-colesanti Phone: +39 06 77274119 Fax: +39 06 77274002 _______________________________________________ Tinyos-help mailing list [email protected] https://www.millennium.berkeley.edu/cgi-bin/mailman/listinfo/tinyos-help
