I want to connect arduino and my app with the HC-05 module but the device isn't showing in the app (my phone is a Samsung S10, Android 12)....I gave the app all the permissions....
I used these blocks mentioned by @Anke in a previous post:
I also tried several other block constructions and also tried the HC-06 module but it still isn't working.
I will appreciate any help!
Post your sketch here.
Where do you read from Bluetooth?
Here is a simple BlueTooth text receiver sample, for single value per line:
Dear @adcgt,
your sketch means your .ino file.
BTW, are you sure that your Arduino hardware is working properly ?
Before further efforts on the app, you can verify the Arduino side by using a ready made app like Serial Bluetooth Terminal (free on google playstore). By installing it on your S10, you can verify if the Arduino+HC05 is transmitting correctly.
Last (but not least) please be sure that the Tx pin of the HC05 is connected to an Rx pin of the UNO and the Rx pin of the HC05 is connected to a Tx pin of the UNO.
