Re: Mobile Broadband - how do I trace/debug the modem initialisation?

Hello Craig,

Yes, this is definitly a modem that falls into the mbm plugin.
I've submitted a patch for it earlier to this list, although that
one requires another NetworkManager patch (changing a bit
how iface/ip_iface is used) as well as a driver which unfortunally
isn't submitted yet (but will hopefully be in the nearest days!)

If you can be patient until next week, I hopefully can describe
howto get this modem going here. I'm dependant on the
driver to be released first.

It's not really a Dell device either, they oem it... ;-)

Tambet, what about the plugins beeing able to specify a
init string and close string? (if the standard wont work that is)

I would believe it to be some other vendor than broadcom.

It probably would be supported by the mbm plugin.
The reason you get errors on atz is because it uses at&f instead (an alias sort of to atz) Also, the modem comes up with cfun=4 (rf disabled) and an cfun=1 makes rf enabled. Doing a cfun=0, which modemmanager currently does as close down, will power off
the modem...

My apologies, you are quite correct, it is a Dell Device: Bus 008 Device 004: ID 413c:8147 Dell Computer Corp. Device Descriptor:
  bLength                18
  bDescriptorType         1
  bcdUSB               2.00
  bDeviceClass            2 Communications
bDeviceSubClass 0 bDeviceProtocol 0 bMaxPacketSize0 64
  idVendor           0x413c Dell Computer Corp.
idProduct 0x8147 bcdDevice 0.00
  iManufacturer           1 Dell
  iProduct                2 Dell Wireless 5530 HSPA Mobile Broadband Minicard Device

The modem defaults to cfun=4 on startup, so one needs to issue a cfun=1 before using it to connect. You are also correct about AT&F working.

What is the mbm plugin?
