Robust BMS - don't buy it for the bluetooth or WIFI

Buy this for the excellent, robust BMS performance don't buy it for the WIFI / Bluetooth performance which I personally couldn't get to work. The BMS is robust, stable and delivers the required power output - my setup is a bit odd so can't confirm the charging aspect. I have tried the supplied wifi dongle and the bluettoth donge and can't get either of them to work which is either due to my incomptance though documentation seems confused. The online apps seem to work I just can't get the bluetooth on my apple phone to connect but as a bms it seems to work well as I have other ways to monitor the battery.
