Hi,
I’m trying to use the lora shield SX1272MB2xAS with a Nucleo F429ZI and connect it to the things network and it’s not working.
I use the mbed-os-example-lorawan .
I already use this example with a disco L072CZ LRWAN1 and it connect to TTN without any problems.
To use the SX1272MB2xAS, I have modified the mbed_app.json with the folowing configuration:
{
"config": {
"lora-radio": {
"help": "Which radio to use (options: SX126X, SX1272, SX1276) -- See config/ dir for example configs",
"value": "SX1272"
},

},
},
"macros": ["MBEDTLS_USER_CONFIG_FILE=\"mbedtls_lora_config.h\""]
}
When I start the program with the trace enable, it seems to work, I get some debug message transmission complete but the OTAA doesn’t work and I’am never connected with TTN.
Is there a bug with the library or should I do something else?
Thank’s in advance for your replies
