Hi everyone,
I want to send data to device (st lora development kit) from lora server. I entered the multicast application seasion key and multicast network session key in this device and loraserver multicast. However, i checked this code with breakpoints, multicast frame came to device and i saw SECURE_ELEMENT_FAIL_CMAC, that is not return to LORAMAC_CRYPTO_SUCCESS so i can not read the data. How can i find this problem ?
This is the multicast init codes:
#define Mc_App_S_Key {0xB5, 0xE2, 0x9E, 0xB7, 0x6E, 0x86, 0x13, 0x21, 0x9D, 0x06,0x84, 0xFE, 0xDA, 0xE1,0x24, 0x91}
#define Mc_Nwk_S_Key {0xB5, 0xE2, 0x9E, 0xB7, 0x6E, 0x86, 0x13, 0x21, 0x9D, 0x06,0x84, 0xFE, 0xDA, 0xE1,0x24, 0x91}
static uint8_t McAppSKey[] = Mc_App_S_Key;
static uint8_t McNwkSKey[] = Mc_Nwk_S_Key;
