Apps Receiving Data From a Watch to a Phone

[haroldjclements]

Hello forum, I am struggling with this for a day. I have tried all I can find on the internet, but obviously I am not getting it.

I have a watch app that once you press a button should sent a "pice of text" to the phone. However I can not get it to work.

All the code and log statements return good from the watch - it finds the mobile and does not return an error. I dont get any of the log statements from the mobile code and nothing happens (no toast).

Any help will be very gratefully received as I am at the end of my tether !!!!

Kind Regards,
Harold Clements
