[Openbts-discuss] GPRS problem on other devices than phone

[Marcin D. <mar...@cy...>]

Hello,
I have GPRS connection running perfectly on mobile phones. I wanted to
try it with another device using cellular connection and every time the
device tries to send data I see this kind of messages in logs:

And the connection is not established.
Any ideas what may be the reason or how to debug it to find more about it?
