Hi,
I met a similar problem on both Treo 600 and Treo 650
using the HTTP lib with GPRS connections, also reproduced with the HTTPLibTest
sample: if the radio was not on before using the sample, the device would reboot
randomly while establishing the GPRS connection, or right after, or while using
it, or even when leaving the sample.
Basically, and as far as I undestood, the trouble is
the SIM card is not fully ready for a GPRS connection right after unlocking.
Thus, you can't rely on the NetLibOpen() API to simultaneously turn the radio on
and establish the GPRS connection, as the HTTPLibTest sample does.
Instead, you should:
- use the
PhnLibModulePowered() API to check the radio status
- if radio is off, use
the PhnLibSetModulePower() API to turn it on
- use the PhnLibGetSIMStatus()
and PhnLibRegistered() APIs to check the SIM status and *wait* for the SIM to be
registered and ready
Then the NetLibOpen() API can safely establish the
GPRS connection.
Hope it helps.
Regards
Vinc

Subject: Re: NetLibOpen Fatal Exception
on a Treo 650
Update:
Right now, it seems to cause a fatal exception
without fail when I call NetLibOpen on the Treo 650 and am not yet connected
to the phone network. It asks me if I want to connect to the phone
network, connects, and then resets before it would connect to the data
network.
Everything seems to work fine if I'm already connected to the
phone network.
Does anyone have any ideas? Or even some help on
how I should go about trouble shooting this? It is driving me
mad...
Has no one seen this happen before?

It never seemed to do this on the 600, and it only happens
sometimes on my 650. The 650
is on the Cingular network; the 600 was on Sprint.
Anyone have any
ideas?
