[dongle0] timedout while waiting 'OK' in response to 'AT+COPS?'

[Israel Padron]

Hello,

I´m triying to setup 10 Huawei K3765 with chan_dongle and asterisk 11.9.0 on a Raspberry Pi B model. After plug 3 modem, I start receiving those warnings on console:

[dongle0] timedout while waiting 'OK' in response to 'AT+COPS?'

The modems goes offline and online, and also asterisk console freezes some seconds.

My chan_dongle configuration is:

[general]

interval=15                     ; Number of seconds between trying to connect to devices

;------------------------------ JITTER BUFFER CONFIGURATION --------------------------

;jbenable = yes                 ; Enables the use of a jitterbuffer on the receiving side of a

                                ; Dongle channel. Defaults to "no". An enabled jitterbuffer will

                                ; be used only if the sending side can create and the receiving

                                ; side can not accept jitter. The Dongle channel can't accept jitter,

                                ; thus an enabled jitterbuffer on the receive Dongle side will always

                                ; be used if the sending side can create jitter.

;jbforce = no                   ; Forces the use of a jitterbuffer on the receive side of a Dongle

                                ; channel. Defaults to "no".

;jbmaxsize = 200                ; Max length of the jitterbuffer in milliseconds.

;jbresyncthreshold = 1000       ; Jump in the frame timestamps over which the jitterbuffer is

                                ; resynchronized. Useful to improve the quality of the voice, with

                                ; big jumps in/broken timestamps, usually sent from exotic devices

                                ; and programs. Defaults to 1000.

;jbimpl = fixed                 ; Jitterbuffer implementation, used on the receiving side of a Dongle

                                ; channel. Two implementations are currently available - "fixed"

                                ; (with size always equals to jbmaxsize) and "adaptive" (with

                                ; variable size, actually the new jb of IAX2). Defaults to fixed.

;jbtargetextra = 40             ; This option only affects the jb when 'jbimpl = adaptive' is set.

                                ; The option represents the number of milliseconds by which the new jitter buffer

                                ; will pad its size. the default is 40, so without modification, the new

                                ; jitter buffer will set its size to the jitter value plus 40 milliseconds.

                                ; increasing this value may help if your network normally has low jitter,

                                ; but occasionally has spikes.

;jblog = no                     ; Enables jitterbuffer frame logging. Defaults to "no".

Any idea, how to make 10 dongles work same time without disconnects/freezes?

Thanks in advance,

Israel.

Hey,

Try to use an external usb hub with a power supplier.
It should fix the problem.

Best regards

Hello Israel,

It is good have news about you.

We talk about it, a few months ago, a few people feel the same with raspbery, normaly it is a problem about power, but with raspberry it is like a problem with USB hub.

Please try your configuration with a "big" computer :- )

ehh, que te echamos de menos por estas tierras ;-)

Best regards.

Jorge.

I have almost the same problem but my RPi(Rev B) works correct up to 3 modems. After attaching 4 modem, devices in /dev/ are created and sytem works. After adding dongle in asterisk, system is unstable, temporarily freezing, modems timedout ...

I have 2 powered USB hubs and i have tryied all combination (all dongles in hub1, 2; split dongles into both hubs; hubs paralel, serial,..) without success.

I have heard about some USB issues in Raspberry but I dont known that these are responsible

My config with 3 modems

modems Huawei K3765

Hey Jorge!!

Nice to see you around! I´m using powered 10 port USB Hub, so I think you are right about the problem being from the raspberry. I was looking for a small portable solution, this is why I choose the raspberry, also I have raspberry working for another project (litecoin mining) working with 20 Usb Gridseed per raspberry,

Pronto volveré a la madre patria, para finales de año ya estaré por aquí!  ;)

Un abrazo,

Israel Padrón.
