Join Resquest failure with the b-l072z-lrwan1 discovery kit

[AJT]

Hello,

i'm trying to send data to a server thanks to b-l072z-lrwan1 discovery kit but i can't even start the connexion between them.

Here are the parameters that i've set/chosen on the server :

here is the device parameter according server point of view :

  

and finally the error :

you can find the commissionning.h that i have attached AND the main.c (it's the same main.c as the end node project excepted that i've chenged LORAWAN_DEFAULT_DATA_RATE (DR0 to DR5) and LORAWAN_ADR_STATE (ON to OFF)

Here you can also check the debug frames printed when i launch the program in debug mode :

 

1 means that LoRaMacMibSetRequestConfirm function returns "LORAMAC_STATUS_BUSY"

0 means that LoRaMacMibSetRequestConfirm function returns "LORAMAC_STATUS_OK"

I don't know why i can't send data to the server whereas all key are the same on both sides.

Maybe should i check the the appkey again... any help ?

thanks

regards

Thibaud
