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 ?

AT!GSTATUS?

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”
OK

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

Assume this goes up all the way to B71 (191 → B71)?

What about WCDMA bands? I get
87 (decimal)
when AT!GSTATUS? gives
WCDMA band: WCDMA 900

It is not easy to switch by my self and try what i get. We build three different wp76s for over the world. It would have been nice if the band bitmask on le_mrc API Reference - Legato Docs could have been used, like
if (band == LE_MRC_BITMASK_BAND_WCDMA_EU_J_CH_IMT_2100)
bandstrPtr = “WCDMA2100”;
else if (band == LE_MRC_BITMASK_BAND_WCDMA_US_PCS_1900)
bandstrPtr = “WCDMA1900”;
etc, etc
! But that was maybe not the intended use? It could be good with a clarification in the docs then on how to know the band.

We can’t run the AT!GSTATUS? now, since the atClient has problems in R17 and we want to avoid AT as much as possible as it drags any connected applications with it when it crashes.

you can refer to the following:

80 → WCDMA 2100
81 → WCDMA PCS 1900
82 → WCDMA DCS 1800
83 → WCDMA 1700 (U.S.)
84 → WCDMA 850
85 → WCDMA 800
86 → WCDMA 2600
87 → WCDMA 900

120 → LTE Band 1
121 → LTE Band 2
122 → LTE Band 3
