Fibocom L860-GL TypeError modem is undefined #15

GektorUA · 2023-10-04T13:06:57Z

Can't open main modemband page for selecting bands on Fibocom L860-GL, always get this:

Have try different ports by changing it in config file:

but nothing helps, USB modem info:

Hi @GektorUA ,

Configuring/reading bands from the console works OK?

Everything should work for the "/dev/ttyACM2" port, from the error I can see that there is a problem with recognizing the modem.

Show result of the command:
sh -x /usr/bin/modemband.sh getinfo

GektorUA · 2023-10-12T08:45:41Z

I have re-flash firmware of modem, seems now i can get it load, but sometimes page still did not open, and same with 3ginfo, it's refresh by themselves and did not show any info, need to press F5 few times and wait, then it show few seconds and refresh themselves again and info disappear. I can send video of that.

Hi @GektorUA,
The latest package updates I've done should eliminate errors in the modem's bandwidth reading problem. Replace TypeErrors with messages for user. They did not improve communication with the modem in any way.

@obsy Cezary mógłbyś zerknąć. Testowałem to u siebie wiadomo na innym modemie, ale u mnie po podaniu zmiennej "_DEVICE" dostaję:

+ . /usr/share/modemband/2c7c0801
+ _DEVICE=/dev/ttyUSB2
+ _DEFAULT_LTE_BANDS='1 2 3 4 5 7 8 12 13 14 17 18 19 20 25 26 28 29 30 32 34 38 39 40 41 42 43 46 48 66 71'

Przykład wyżej wygląda tak jakby skrypt nie wykrywał modemu.

obsy · 2023-10-13T11:24:02Z

@GektorUA could you show us:

GektorUA · 2023-10-14T14:09:44Z

@GektorUA could you show us:
/usr/bin/modemband.sh json

It's sometimes out:

and sometimes:

I have try different two COM ports (ttyACM0 and ttyACM2), both are not busy.

obsy · 2023-10-14T14:15:02Z

So the problem here is that sometimes you can't get a read from the port. Either you have this port occupied by another process (like smstools3, 3ginfo etc), or the modem is hanging and there is not much you can do about it.

GektorUA · 2023-10-14T14:22:47Z

I have 3 modems (Fibocom L860) in one system, all of them working identically with modemband and 3ginfo.
I am not using smstools or modemmanager, 3ginfo page not opened in same time with modembands page, i have run minicom and check - there is no output and i can run commands without interrupts, so - COM ports are not busy.

obsy · 2023-10-14T14:26:34Z

Run this via ssh:

for i in $(seq 0 1000); do
 sms_tool -d /dev/ttyACM2 at "at+xact?"
done

GektorUA · 2023-10-14T14:39:26Z

There is much output, where i can send it?

obsy · 2023-10-14T14:43:00Z

No need, just check that each line is correct.

GektorUA · 2023-10-14T14:44:30Z

for i in $(seq 0 1000); do echo "$i" && sms_tool -d /dev/ttyACM2 at "at+xact?"; done
mainly, it same at each line:

obsy · 2023-10-14T14:56:10Z

Reading line by line works. I have no idea why reading sometimes fails.

GektorUA · 2023-10-14T15:00:01Z

I think it's something related to frontend with backend synchronization...
Because, with 3ginfo i have issues too.

4IceG · 2023-10-15T13:19:49Z

Something must be absorbing the modem if it doesn't want to respond to at commands.
I have a Quectel modem and it doesn't always respond right away, but it does in 98% of cases.

GektorUA · 2023-10-17T22:10:13Z

I have switch to modeminfo, there is no issues with Fibocom at all.

obsy · 2023-10-18T08:45:03Z

Run again:

/usr/bin/modemband.sh

if there is still no data, do this:

sed -i 's/sms_tool/sms_tool -D/g' /usr/share/modemband/8087095a

And show us

sh -x /usr/bin/modemband.sh

run it several times if necessary, I am interested in knowing what the modem returns when there is no data.

Change to /dev/ttyACM2, not ACM3.

This is strange, because you did the commands a thousand times and it returned fine. Now at some point it only returns "ok" without the command result.

GektorUA · 2023-10-18T17:40:57Z

I have 3 modems in my system, ttyACM3 is first port of second modem.

obsy · 2023-10-18T18:12:59Z

You previously tested /dev/ttyACM2, so what you showed now comes from a different modem, right?
Ehh, so retest all command on the same modem...
