epicycle Posted March 21, 2019 Report Share Posted March 21, 2019 Hello, one of my dna 250/166/167 2-Cell doesn't work as soon as I install any firmware higher than sp5 (sp5.1, sp6). As soon as the newer firmware is applied I get "check atomizer" when firing and the atomizer analyzer shows question marks for the ohm values. When I rollback to SP5 everything works fine again. Any ideas what the issue could be? The chip i have no issues with has the following production history: Saturday, May 6, 2017, 12:41 PM The one that seems to have issues with sp5.1/sp6 has the following production history: Wednesday, January 11, 2017, 1:41 PM Link to comment Share on other sites More sharing options...
James Posted March 22, 2019 Report Share Posted March 22, 2019 If you go into Serial Terminal, what do you get as responses to these commands (after trying to fire)? I=GET OFFSET V=GET OFFSET Thanks! Link to comment Share on other sites More sharing options...
