This function should be called only after a successful call to nm_bsp_init.

sint8 nm_bsp_deinit ( void  )

De-iInitialize BSP.

This function is used to de-initialize the BSP and turn off the WINC board.

Returns
0 in case of success and -1 in case of failure

The nm_bsp_deinit is the last function that should be called after the application has finished and before the WINC is switched off. A call to this function will turn off the WINC board by setting CHIP_EN and RESET_N signals low. Every function call of nm_bsp_init should be matched with a call to nm_bsp_deinit. Failure to do so may result in the WINC consuming higher power than expected, since it won't be properly de-initialized.

Precondition
The BSP should be initialized through nm_bsp_init first.
Note
Implementation of this function is host dependent.
Warning
Omitting this function may lead to unknown behavior in case of soft reset.

Returns
The function returns M2M_SUCCESS for successful operations and a negative value otherwise.
