I've bought an optical probe(Bluetooth optical probe OP-700 for smart metering) for reading electricity meters.
I connected it to my PC and in Arduino IDE opened serial monitor on the specified port, after sending 'AT' command I've got nothing from the device.Now I'm wondering that is it possible to change baud rate of this device with IDE ? if not , how can I adjust it? because in its catalog it said that the baud rate is adjustable.
