brp_errcode brp_BlePeriph_GetCharacteristic	(	brp_protocol	protocol,
		unsigned	CharacteristicNdx,
		brp_buf *	CurrentValue,
		size_t *	CurrentValue_len,
		brp_mempool *	mempool
	)

This command retrieves the current value of a characteristic. A characteristic will be initialized to 00 00 ... 00 when calling BlePeriph.Enable and will be modified by either the BRP host (BlePeriph.SetCharacteristic) or the BLE Central (via a write to the characteristic).

Parameters

[in]	protocol	used to execute the command
[in]	CharacteristicNdx	The index of the characteristic to be retrieved in the Characteristics array passed to BlePeriph.DefineService
[out]	CurrentValue
[out]	CurrentValue_len
[in]	mempool	is used to store response data. Maybe NULL to use an internal mempool, in this case the data is only available until another command uses the internal mempool
