Hi all,
any progress on the "507" error?
I also want to connect an MITinventor project to a HC-05 Bluetooth module.
Any of the suggested projects does not work. It will come up with the " ERROR 507. Unable to connect"
There is only one app, Arduino Bluetooth Controller ( HM-10 Module), that does connect to the HC-05. But unfortunately I can not alter the app to my usage.
What is the general problem with " Error 507" ?
Regards
Andreas
