Sierra Wireless MC7354

[Pablini]

Hi,

I understand that Quectel uses the same Qualcomm sims as Sierra Wireless. I will like to test this in MC7354 and EM7565 Modems.

I cant see anything in UDP/4729 in Wireshark, Im getting this output in the MC7354 modem:
ppratsc@QUARKS-V:~/apps/em7565/diag-parser$ sudo ./diag_parser -g localhost -i /dev/ttyUSB0

Exactly the same problem with EC20-A

In diag_init.c:WRITE could you log "len" instead of "sizeof(esc)/sizeof(esc[0])"? Also the tty (e.g. use the stty application to dump it) config for /dev/ttyUSB0 would be interesting and make sure you are on a diag UART?

Thank you Zecke for the quick answer.

This is how dmesg detect the EC20-A:

[33991.723480] qmi_wwan 1-1:1.4 wwp0s20f0u1i4: renamed from wwan0
------------------------END-----------------

Also I understand that /dev/ttyUSB0 is the DIAG port.

I will dump tty and diag_init....

regarding the Diag UART, how can I be sure?? is there any hardware change I need to make?

regards,
