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'

It’s 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?

Regards,

Caleb

Subject: Re: GPRS not coming up on NanoBTS 140

Can you post your firmware versions?

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

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.
I've taken some log captures:

OpenBSC Startup:

In the nano startup - the two things that stand out are the complains
about flag 3 and the NSE:

27855:DBG:OAM_IM:roleInstanceProcClearContaineeFlags: BTS:0 flag 3 not
setting or set!
27855:DBG:OAM_IM:roleInstanceProcClearContaineeFlags: GPRS NSE:0 flag
3 not setting or set!

42142:DBG:GBHSS_STACK:bgp_error_reporter() : PROTO_ERR:
Msg=GPRS_BGP_RL_UL_UNITDATA_REQ, Err=GPRS_NSEI_NOT_OPERATIONAL
42142:DBG:GBHSS_STACK:bgp_process_msg failed :
msg=GPRS_BGP_NM_BVC_RESET_REQ err=GPRS_NSEI_NOT_OPERATIONAL

Any thoughts or additional data points I should collect?

Thanks,
Gus
