[Openbts-discuss] broadcast message script? Re: OpenBTS often can't be found

[Joe M <jm...@gm...>]

Hi all,
I manage to change the ARFCN and, tweak the RSSI target and the noise
level. It works now and very stable.
I can see and connect with my phone easily and able to get messages quite
fast.

Now, I wonder is there a way I can send broadcast messages to all connected
MS.. is linux script would be the only option? has anyone created such
script?

regards,
Joe
