Can you help me with some extra details please:
1. Do you have functionality for bladerf?

Thank you for the outputs John

To establish the GPRS connection the UE needs to send GPRS attach request.
In the traces , the UE is not sending this message when its expected to see

Please see this picture for working GPRS in NiPC lenovo mobile

You can use the wireshark filter: gsm_a.dtap.msg_gmm_type  in the traces
