le_mrc_GetRadioBandInUse

1

le_mrc_GetRadioBandInUse() returns 121

How is that related to any of the !GSTATUS, is there a lookup table or something ?

do you mean le_result_t is getting 121?
can you paste your code implementing le_mrc_GetRadioBandInUse() here?
What is the current setting on your side on the followings?


ati3
AT!ENTERCND="A710"
AT!band?
AT!BAND=?

It is the bad variable that gets set to 121

uint32_t band = 0;
if (le_mrc_GetRadioBandInUse(&band) != LE_OK)
band = 0;

band is 121

AT!ENTERCND=“A710”

on my side, my wp7605 module is registered in LTE B3, but this API return 122

This issue has been reported internally

As workaround, please use AT command

See below for the conversion of returned value and LTE band number:


120 -> LTE band 1
121 -> LTE band 2
122 -> LTE band 3
123 -> LTE band 4
124 -> LTE band 5
125 -> LTE band 6
126 -> LTE band 7
127 -> LTE band 8
128 -> LTE band 9
129 -> LTE band 10

Thanks that will work
