I'm probably a rare case but I successfully burn the bootloader (atmel 328p stand alone with slimeNode board) using atmel studio7 with an AVRMK2ISP, flash the mySensors code using arduino IDE and the "nodeManager" libraries succesfully too and everythings appear properly in my HomeAssistant, very nice, I've just give a paypal tips ;o) But I have no idea why I use this bootloader ??? If I used a nano, I wont change the bootloader ? Is there something better ? It could look stupid but their is no real explain about WHY I must change my bootloader on this page...
