Function Documentation#
sl_si91x_gcm#
sl_status_t sl_si91x_gcm (sl_si91x_gcm_config_t * config, uint8_t * output)
To encrypt or decrypt the message according to the given configuration.
Parameters
| Type | Direction | Argument Name | Description |
|---|---|---|---|
| sl_si91x_gcm_config_t * | [in] | config | Configuration object of type sl_si91x_gcm_config_t |
| uint8_t * | [out] | output | Buffer to store the output. |
This is a blocking API. Note
The maximum message length supported is 1400 bytes. The M4 receive buffer is limited to 1400 bytes, so both the packet length and expected output must stay within this limit. If the output exceeds 1400 bytes, the NWP will return an error.
Returns
sl_status_t. For more information on status codes, refer to SL STATUS DOCUMENTATION.
