Telit HE910 initialisation sequence freezes

Telit HE910 initialisation sequence freezes

Hi everyone,

I am using the Telit HE910 modem with the "telit: rework for HE910" patches
shared by Jonas Bonn on the 4th of april 2013.

After some endurence testing I realize that sometimes (around 25% of the
time) the initialisation process freezes after switching sim state satus to
2.
I assume that the driver then waits for a signal from the modem, but this
signal never comes.
When this happens, the only way I found is to hard-reset the modem...
Is there a way to stimulate the modem in order to continue the
initialisation sequence ?

Thanks in advance,

Etienne

What's the firmware version of your modem? I noticed that behaviour with 
firmware versions below 12.00.003.

Hi Christopher,

I don't know exactly what firmware version we are using today. I know
however that we will be able to update to version 12.00.024
I hope that it will solve our problem, I will keep you updated.
