 - `OT_ROLE_ROUTER`: The device operates as a Thread Router.
 - `OT_ROLE_LEADER`: The device operates as a Thread Leader.
 
-## Struct: `ot_cmd_return_t`
+### Struct: `ot_cmd_return_t`
 
 This structure represents the return status of an OpenThread CLI command:
 
 - `errorCode`: An integer representing the error code (if any).
 - `errorMessage`: A string containing an error message (if applicable).
 
-## Function: `otGetDeviceRole()`
+### Function: `otGetDeviceRole()`
 
 - Returns the current role of the device as an `ot_device_role_t` value.
 
-## Function: `otGetStringDeviceRole()`
+### Function: `otGetStringDeviceRole()`
 
 - Returns a human-readable string representation of the device role (e.g., "Child," "Router," etc.).

+### Function: `otGetRespCmd(const char* cmd, char* resp = NULL, uint32_t respTimeout = 5000)`
 
 - Executes an OpenThread CLI command and retrieves the response.
 - Parameters:
   - `cmd`: The OpenThread CLI command to execute.
   - `resp`: Optional buffer to store the response (if provided).
   - `respTimeout`: Timeout (in milliseconds) for waiting for the response.
 
-## Function: `otExecCommand(const char* cmd, const char* arg, ot_cmd_return_t* returnCode = NULL)`
+### Function: `otExecCommand(const char* cmd, const char* arg, ot_cmd_return_t* returnCode = NULL)`
 
 - Executes an OpenThread CLI command with an argument.
 - Parameters:
   - `cmd`: The OpenThread CLI command to execute.
   - `arg`: The argument for the command.
   - `returnCode`: Optional pointer to an `ot_cmd_return_t` structure to store the return status.
 
-## Function: `otPrintRespCLI(const char* cmd, Stream& output, uint32_t respTimeout)`
+### Function: `otPrintRespCLI(const char* cmd, Stream& output, uint32_t respTimeout)`
 
 - Executes an OpenThread CLI command and prints the response to the specified output stream.
 - Parameters:
   - `cmd`: The OpenThread CLI command to execute.
   - `output`: The output stream (e.g., Serial) to print the response.
   - `respTimeout`: Timeout (in milliseconds) for waiting for the response.
 
-## Function: `otPrintNetworkInformation(Stream& output)`
+### Function: `otPrintNetworkInformation(Stream& output)`
 
 - Prints information about the current Thread network to the specified output stream.
 - Parameters:
