OK am testing the mobile app with C123 using real sim but getting some odd behaviour (have tested with main branch & sylvian testing branch and results have been similar to this) The results below are from using sylvian testing branch build as described here http://bb.osmocom.org/trac/wiki/SIMReader <http://bb.osmocom.org/trac/wiki/SIMReader> config tx is enabled etc I can download the layer1 firmware to the phone ok - mobile app seems to run ok aswell but when I try to make a call or sms this is where there's some odd behaviour . On my first attempt to make a call I can hear the call trying to be made but an automated message is played saying I have dialed an incorrect number (this normally happens if the number is dialed in an incorrect format) In previous attempts I have tried all the formats I can think of but have never been able to get a successful call to go through as of yet but if I dial it through the phone (without osmocom) normally everything works fine.. 07780000000 +447780000000 447780000000 00447780000000 Usually after the first call the phone then mysteriously deregisters from the network there is no service and when I restart osmocon/mobile etc I still cannot register on the network it just keeps scannning frequenceies and failing to connect with the network. On my first osmocon log when i managed to connect to the network after the call was released there were alot of DSP Error Status: 32 messages and then no service. I have gone through the logs but I still can't figure out why a) the call is failing to go through correctly b) why it seems like I get kicked of the network if I try to make a call Here are my full outputs 1ST ATTEMPT - MANAGED TO PLACE CALL THEN CONNECTION DROPPED Osmocon output - https://www.box.com/s/xdqi7azezprf4g7erz9h <https://www.box.com/s/xdqi7azezprf4g7erz9h> Mobile output - https://www.box.com/s/gqcdas9eqso0nchat011 <https://www.box.com/s/gqcdas9eqso0nchat011> Telnet output - https://www.box.com/s/lcazgabtmous0xheklmc <https://www.box.com/s/lcazgabtmous0xheklmc> 2ND ATTEMPT - FAILED TO CONNECT Osmocon output - https://www.box.com/s/c42vi7ows8p14h0hr45m <https://www.box.com/s/c42vi7ows8p14h0hr45m> Mobile output - https://www.box.com/s/eqygysqommur46ywgqrs <https://www.box.com/s/eqygysqommur46ywgqrs> Telnet output - https://www.box.com/s/kmympl0g0l8zb3xjyu8d <https://www.box.com/s/kmympl0g0l8zb3xjyu8d> 3RD ATTEMPT - FAILED TO CONNECT Osmocon output - https://www.box.com/s/gb9aw9p05pqy1v5fpxke <https://www.box.com/s/gb9aw9p05pqy1v5fpxke> Mobile output - https://www.box.com/s/llo751tuvvu1p5v31eur <https://www.box.com/s/llo751tuvvu1p5v31eur> Telnet output - https://www.box.com/s/t8e63lqrad87f35uylge <https://www.box.com/s/t8e63lqrad87f35uylge> Extract from telnet OsmocomBB# % (MS 1) % Trying to registering with network... % (MS 1) % On Network, normal service: Guernsey, T-Mobile show ms MS '1' is up, service is normal IMEI: 35972800609#### IMEISV: 359728006093#### IMEI generation: fixed automatic network selection state: A2 on PLMN MCC=234 MNC=30 (Guernsey, T-Mobile) cell selection state: C3 camped normally ARFCN=628(DCS) MCC=234 MNC=30 LAC=0x084f CELLID=0xf65d (Guernsey, T-Mobile) radio ressource layer state: idle mobility management layer state: MM idle, normal service OsmocomBB# call 1 +44772228#### OsmocomBB# % (MS 1) % Call has been released % (MS 1) % On Network, normal service: Guernsey, T-Mobile call 1 +44772228#### % (MS 1) % Searching network... show ms % (MS 1) % On Network, normal service: Guernsey, T-Mobile call 1 44772228#### OsmocomBB# % (MS 1) % Call is proceeding % (MS 1) % Call is alerting % (MS 1) % Call: Remote hangs up % (MS 1) % Trying to registering with network... % (MS 1) % Trying to registering with network... % (MS 1) % Searching network... % (MS 1) % No service. % (MS 1) % Power off!
