My bluetooth module is connected to arduino nano using voltage delimiter (to get 3.3V) exactly as its said in this article. I connected it to my phone and was able to communicate with it through bluetooth terminal. Then I uploaded another script which didnt use bluetooth at all though the module was still connected. When I uploaded my previous script for serial communication (from the same article) I found out that I cant see my bluetooth module anymore though it was still working and responsing to commands from usb serial port (in AT mode). I tried resetting it (AT-RESET) and chaning modes but nothing helped. Has anyone faced this problem? How did you manage to solve it? (sorry for my bad english)
