Can I create Characteristic with Notification only, no Read, no Write
I can remove the //char_md.char_props.write = 1; and only the Read and Notify Properties show up in MCP (or the iPhone)
When I comment out the char_md.char_props.read = 1;
Advertising stops and I can not connect to the device.
All I need is a Notification. The server collects data on three (3) sensors, and sends the data using three (3) services. 6-bytes per service, nonstop.
So actually one characteristic with a Notification per service.
Note: I guess eventually with a client app, one would Enable the Notification, and then ignore the Read property.
Any help appreciated
