Im having a supreme 10 with the current firmware, 663_09gg.FSU001
Though i dont know much about firmware…i realised that when i type commands such “AT+WIOM=2” it returns “Error”. Im thinking its a limitation due to outdated firmware. I using WIOM codes for my open AT application and thus i need them.
Ive tried to upgrade firmware with dwlwin but i get the following error message “Boot failure: unknown baseband or unexpected answer received”. So do i really need to upgrade the firmware, and how?
