My system is working correctly in NB-IoT, but it’s quite slow: 10-20 kbps DL. From this, I fear it’s working in NB1 (and not NB2). Could I get some modem status to know if it’s using NB2 ? Does this depend only from network (Amarisoft emulator) to use NB2 or do i need some configuration/band inside modem ?
yes , as you said , BG95 support NB1 and NB2 both ,
but you know , 3Gpp R13 support NB1 only ， if local network is R13 network， the module will work on NB1
if local work is R14 network ， NB2 will have higher priority than NB1
