Can I create Characteristic with Notification only, no Read, no Write

Question

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

Bjørn,
Yes, I mean updating the characteristic, not en/disabling of Notification. 
 I actually just tested it.
I call 
 void our_termperature_characteristic_update(ble_os_t *p_our_service, int8_t *temperature_value) 
 which calls
sd_ble_gatts_hvx(p_our_service->conn_handle, &hvx_params); 
 I call three (3) Characteristic updates in succession sv(1..3)_termperature_characteristic_update()
One after the other, no delay, and it seems to work. 
 In between the three updates, there is timer delay. 
 I decreased the timer interrupt to 1ms in between the tree calls, just to test, so all looks good.
In the real world I have this timer set to 2 or 3 seconds. 
 I assume something else was wrong earlier. 
 Thanks
