sd_ecb_block_encrypt returns error

[dawn]

		nrf_ecb_hal_data_t encryption_parm;
	memset(&encryption_parm, 0, sizeof(encryption_parm));
	 memcpy(encryption_parm.key, encryption_key, sizeof(encryption_key));
	 memcpy(encryption_parm.cleartext, clear_text, sizeof(clear_text));
	 memcpy(encryption_parm.ciphertext, cypher_text, sizeof(cypher_text));
	//encryption_parm
	err_code=sd_ecb_block_encrypt(&encryption_parm);
	APP_ERROR_CHECK(err_code);

Above is the code for AES encryption. The code resets when APP_ERROR_CHECK function is executed. Should I set any other parameters or use any function before calling the d_ecb_block_encrypt function. Encryption function is called before initializing the BLE stack.

what error code do you get?

[dawn]

After calling the encryption function the ciphertext array was empty

[Susheel Nuguru]

what do you mean by Encryption function is called before initializing the BLE stack You need to enable softdevice to use this SVC function otherwise this function will return with error 0x2

#define NRF_ERROR_SOFTDEVICE_NOT_ENABLED      (NRF_ERROR_BASE_NUM + 2)  ///< SoftDevice has not been enabled

sd_ecb_block_encrypt() is called before ble_stack_init() function

[Susheel Nuguru]

You have your problem. sd_ecb_block_encrypt is not available before the stack is enabled. Call it after ble_stack_init() and it should work.
