[srslte-users] Decoding SIB messages

[Edward Johnson]

Dear Antonio,
in pdsch_ue example, SIB1 messages are founded but not printed. You can see
it at line 693:

*/* We are looking for SIB1 Blocks, search only in appropiate places */*
*if((sfidx == 5 && (sfn%2)==0) ||mch_table[sfidx] == 1){*

from that, if you perform a successful call to srslte_ue_dl_decode ( aka,
its return value is bigger than 0), you can print the SIB1 via
srslte_vec_frpintf_byte.

Hope you can find this helpful.

Regards,
Ed
