Thanks for this explanation. I read it through and understood we need to maintain CTS at a good level during sleep in order to get any wake signal from GSM firmware. > Now Matt are looking into the GSM suspend(sleep) current too high issue, > this might be firmware configuration or we do something on the Samsung > CTS/RTS behavior side. Ah this is the first I heard of this as an issue on its own. What is the measured current for GSM module powered but in sleep right now that we looked at and said: "too high"? - -Andy -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (GNU/Linux) Comment: Using GnuPG with Fedora - http://enigmail.mozdev.org iD8DBQFHsqS3OjLpvpq7dMoRAnz7AJ9CE8mbFgaW2d76Zn94vTSVzR8v+ACgjiUI G6SwhEWPSxa00v4aq4N41YQ= =R5O/ -----END PGP SIGNATURE-----
