[Openbts-discuss] Signal Strength

[Andrea I. <pau...@ho...>]

Hello everyone,I am developing for a first time a simple application with OpenBTS (v5.0).Now I am able to retrieve the list of devices with the 'tmsis' command, where I can find the IMSI/IMEI list. I wish to get the associated uplink signal strength for each device. Does anyone knows how can I do this?I tryied two different ways. 1) the command 'chans': that returns an empty table2) the "JSONEventsClient" app: that returns a lot of useful stuffs. Here seems that I can find what I am looking for, but every times the IMSI field has "no-MMUser" as value. Here it is a sample log for both instructions:OpenBTS> tmsisIMSI     TMSI     IMEI            AUTH CREATED ACCESSED TMSI_ASSIGNED 2*****       -       3******                     2           107s          107s               0

Thank you,Andrea
