RE: mmcli "--timeout=[SECONDS]" does not work with --simple-connect

[Amol Lad]

Hi Aleksander,

I think the reason is the "60" seconds timeouts configured in 
register_in_3gpp_or_cdma_network() in mm-iface-modem-simple.c.

Now, how do we handle scenarios where network takes more than 60 seconds to 
register? --simple-connect will always timeout..

Please advise.

Hi Aleksander,

I've tried with MM 1.20.4 and also 1.18.8 but it seems the timeout is always 
"60 seconds" even if a larger --timeout is provided to mmcli --simple-connect

Any suggestion will really help. I landed into this issue because here a 
network on roaming is taking around 90 seconds to register and I found mmcli 
--simple-connect is returning after 60 seconds wait even though I've provided 
--timeout=175

# time mmcli -m 0 --timeout=175 --simple-connect="apn=vi" -v
