I am using Xbc v1-uT001 in bypass mode. I want to activate the 3rd PDP context but I always get activation failed

I want to do an HTTP GET using XBC v1-UT001 in bypass mode.
Activating the 3rd context always results in error: activation failed.
Can you please help?

You need to talk to Telit about that. Digi only supports Digi’s firmware or Entering bypass mode. ALL functions once in bypass mode, are supported by Telit and with an NDA.
