I am having a problems to update some values on the master, I am using bluenrg-1 I have one device working as a master and other as a slave. The slave has a button, I have both connected and every time I press the button on the slave the function aci_gatt_update_char_value() is called containing a value, I have on the slave that configuration:
the master is discovering the service and characteristic from the slave. Do I need to do something more or in a different manner? Which event function will be call on the master?
I can read the values from the master requesting the value every x time once both are connected but I would like to received the value on the master just the button is pressed.
