Hi,
I am working with the EC21 and we can setup a PPP0 communication. The EC21 is coupled with an SBC. And communicates over USB. At spontaneous intervals the communication to the SBC gets corrupted. Wvdial is used on the SBC with the following settings:
[Dialer quectel]
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Init3 = AT+CGDCONT=1,"IP","****"
Dial Attempts = 3
Stupid Mode = 1
Modem Type = Analog Modem
Dial Command = ATD
Stupid Mode = yes
Baud = 460800
New PPPD = yes
Modem = /dev/ttyQUEC3
ISDN = 0
APN = ""
Phone = *99***1#
Username = ""
Password = ""
Carrier Check = no
Auto DNS = 1
Check Def Route = 1
(I have left out the username, password and APN)
I noticed that FCLASS is not in the documentation of the EC21, could this be the issue? Or could the DCD/DTR get corrupted?
Kind regards,
