Hello,
1. Could I please have the latest firmware for RM530N-GL?
Quectel
RM530N-GL
Revision: RM530NGLAAR03A02M4G
OK
2. Could I please also have the latest flash tool?
3. If I wanted to purchase another Quectel model for M.2, what would be the best to purchase that supports USB Audio Class (UAC2) so I can make and receive calls using USB Audio?
