Format of Base station identity code

  1. Hi there!

    I’ve not found any information about format of BSIC in documentation. 

    Is it decimal or hexadecimal?

      1. Hmm.. Then why time from time we receive BSIC in hexadecimal format?

        Example:

        #MONI: N5 C0 07EA 0CA5 516 -91dbm -1 0  

         

          1. But as you see it can be.

            Also after module initialization and during searching for available stations we receive FF BSIC.

            #MONI: Cell  BSIC  LAC  CellId  ARFCN    Power  C1  C2  TA  RxQual  PLMN

            #MONI:  S    45  2778   0228     711   -64dbm  42  52   0     0    life:)

            #MONI: N1    70  2778   0000     685   -87dbm  19  23 

            #MONI: N2    67  2778   0069      70   -89dbm  17  11 

            #MONI: N3    13  2778   0295     709   -94dbm  12  16 

            #MONI: N4    75  2778   0229     698   -97dbm   9  13 

            #MONI: N5    FF  FFFF   0000     695   -80dbm  -1  -1 

            #MONI: N6    FF  FFFF   0000     543   -98dbm  -1  -1 

             

            OK 

             

             


          2. The BSIC is 6 bits in length and composed of a 3-bit network color code (NCC) and a 3-bit base-station color code (BCC).


             


            AT#MONI reports 2 digits (octal) in s
            eparate way e.g. BISC=30 means NCC=3, BCC=0

             

            FF is only reported when the ARFCN is not decoded (no info)

             

            Can you attach the complete log with strange BSIC ?

             

            module used? fw version?

          3. If you mean trac.rtd, unfortunately we can’t get it now.

            As for  module and  fw version:

            GL865-QUAD 10.01.141

          4. It would be interesting to see the output of #MONI and #CSURV (CSURVF=2) for the same channel, when the weird BSIC is reported.

             

            What I can tell you is that I’ve never seen BSIC reported in a different format then octal, except for #CSURV in CSURVF=0 (decimal)

  2. It would be interesting to have whole #MONI=7 output and compare it to AT#CSURV, when you see this weird BSIC value.

     

    What I can tell you is that I’ve never seen BSIC reported in non octal format by #MONI.

    Instead #CSURV reports the BSIC in decimal (#CSURVF=0) and octal (#CSURVF=2)
