I can never connect my id52a to RS-MS1A on Bluetooth. Very discouraging.
There are some incompatibilities in the BlueTooth protocols, particularly some devices only support LE (Low Energy) and some devices have no support for that.
There are some android applications for monitoring wifi and bluetooth signals and reporting what the Android can handle. Using one of those may help figure things out.
I have a OTC connectors for my tablets, and I can connect to the RS-MS1A through a USB serial port connected to that. A tablet may not provide enough power to directly run the USB Serial port, so a powered hub may be needed. Since USB-C no longer needs powered hubs, powered USB hubs are getting more expensive or hard to find. Remember that when you are at the flea-market and see one for sale.
I want to get the bluetooth working though because I can not charge my tablet while the OTC adapter is installed.
Sitting in my parts bin waiting for me to get time to work on it are several TTL to bluetooth modules for Arduinos and several bluetooth USB adapters.
And everything needed to connect my older I-Comm radio serial port to connect to one of the bluetooth modules. Unfortunately it will need 4.5 volts of battery power to run it, and I don't know the current drain yet.
