Which is the best way to send/receive raw data (array ex: uint8 txBuffer; ) from mobile to PSOC4 BLE board.? The data might be a commands.
Which profile i need to choose while creating project?
If you are going to send the user specific data (not related to any standard service) then better to use your customer profile and customer service.
If you want to send 32bytes of data over every transfer then set the MTU size to atleast 35 on both mobile app and PSOC4 BLE side.
give more details about your application.
