Max, I also have a 140 with the same issue, no connection to the SGSN. Below are its specs.
Equipment_Version='140_029_24' Software_Version='120a002_v149b44d0' Its a PCS 1900 unit. Unfortunately I do not have a 139/140 with a working firmware version. Maybe someone else can chime in with a version number that does work with GPRS on the 139/140 models?

I've recently been exploring anomalous behavior which seems to follow firmware version differences; these odd behaviors seem to have the greatest affects on the 139/140 type units used in GPRS-enabled configurations. Inclusive of the issues I've seen are a few 140-model units which simply do not respond to any GPRS-related configurations with a connection to the SGSN. My suspicion lies strongly in the firmware either not supporting GPRS or there being a different mechanism to invoke it. While it may be beyond the scope of the list to discuss issues relating to vendor firmware, I am eager to solicit an off-list discussion with anyone with more "experience" with firmware issues. The ideal end result would ideally be two-fold: 1) To discover how firmware version affects interoperability with openbsc 2) Ultimately help more people get their setups working on the variety of hardware floating out and about -MM On Fri, Sep 30, 2011 at 10:56 AM, Gus Bourg <[email protected]> wrote: Hello all, Looking for ideas. I have a NanoBTS Model 140 which doesn't seem to work with GPRS. It never connects to the SGSN. The openbsc/sgsn environment is ok - I can swap in another nano and it works fine.
