It's a nice try by icom. If you buy the icom cable it works well with icom dstar handhelds. It's terrible with trying to use Bluetooth with 5100. The msz Verison has the same problems o lots of tablets and iPad. I sure wish Icom would fix it.
I connected this app to my 51a Plus I changed some settings and it works perfectly. It's not the most useful app ever seen but it does work I am using a samsung tab e 7 inch tablet with 4.4 Kitkat operating system if you look at other comments for this app you will see the radio settings you need to change there are just a few and it's very simple
I have been unable to get this application operating with my Icom ID-51A Plus radio. When I connect my RS-MS1A cable with my Samsung S2 and try to run the application I get the following start up error message: "Error Failed to communicate with the transceiver. Check the transceiver or application settings." I see from various comments on Youtube that I am not the only one with this problem. So far I am out $80 for a cable that doesn't seem to work. Does anyone have any ideas what the problem might be? UPDATE: I finally got the damn thing working. You have to follow the instructions in the ADVANCED PDF manual (not the small paper manual that you got in the box with the radio). Your radio's CD has the advanced manual on it or you can download it from Icom. What you have to do is go to section 16 in the advanced manual and follow the instructions for turning the data jack on. See page 16-76 of the advanced manual. Follow those instructions and it will work just fine. It's really ridiculous that this information wasn't included with my RS-MS1A cable. It would have saved me a lot of time and aggravation. I'm docking it one star for this "oversight."
Connected to IC-7100 using cable supplied with rig. The app does nothing. Waste of time.
Works well on a Galaxy S4 and Dell Vue tablet - but you do need to turn on C-IV communications on your ID51Plus or similar device.
Doesn't work on Samsung Buyer Be Ware This app does not work on either my Samsung S6 Edge or my older NOTE 8.0. Do NOT waste your money on the Icon OPC-2350LU or this App if you own either, as they will NOT work. The best you can hope for is an error message, "Failed to communicate with the transceiver. Check the transceiver settings or application settings.". To the extent I am able, I have checked both the transceiver and applications settings and made changes, yet nothing. Very disappointed.
・The ID-31A/E PLUS is now compatible with the RS-MS1A.
