Hi.I am using an arduino uno for my garden .Unfortunately I can’t get wifi connectivity upto my garden nor can I afford a new GSM Shield … So I would like to use my bluetooth HC-05 for watering my plants when I go there . But If I load the HC-05 example My phone does not connect even if if I am paire tho the bluetooth module . How can I use my HC-05 to control my pump which waters my plants.?
Is your device available on bluetooth scan dialog?
What app’s version are you using? and what smartphone are you using?
Have you also connected to that paired module, from within the BT widget settings - in your app?
It does appear in the scan log .I’m using the latest version.
