B-L072Z-LRWAN1 module and use AT commands

Hello,

I have a B-L072Z-LRWAN1 module and use AT commands, but I do not know how to change the frequency I need 915Mhz, but when I use the command AT + TCONF =? It shows me the following:

Freq = 868 MHz

Power = 14 dBm

Bandwidth = 125 kHz

SF = 12

CR = 4/8

LNA State = 0

PA Boost State = 0

868: 14: 125: 12: 4/8: 0: 0

then I change the compilation options, but there are no changes when executing this command, that is, the frequency always shows it in 868Mhz

Hard coded constant in

STM32CubeExpansion_LRWAN_V1.1.2\Projects\Multi\Applications\LoRa\AT_Slave\src\test_rf.c

static s_loraParameter_t loraParam= { F_868MHz, P_14dBm, BW_125kHz, SF_12, 4, 0, 0};

Thank Clive, now work fine:

AT+TCONF=?

Freq= 915 MHz

Power= 14 dBm

Bandwidth= 125 kHz

SF= 12 

CR= 4/8 

LNA State =0  

PA Boost State =0  

915:14:125:12:4/8:0:0

So, there are a documento where this level of setting is show?

Thanks

I just searched the source files with a file manager.

Looks to have been overlooked, probably needs to use the define set elsewhere for the frequency.

This bug has been there for a while, not seen any questions on the forum about it before.
