I am wandering why I cannot use HC-06 ?
Iām asking because i have one somewhere at home and i was thinking about trying it.
Maybe you can – I have HC-05 and HC-06 and I’ve had no luck getting the HC-06 working this way. But, that’s not to say you can’t. I have had my fill of HC-06 devices and just don’t bother with them any more. I tried using one for my second TinyG but it wasn’t having any of it, so I went back to the HC-05 and had it working in about 2 minutes.
The process should be the same, so following these instructions should be right.
From the Wiki:
The modules with the HC-03 and HC-05 firmware are the Master and Slave integrated Bluetooth serial modules with firmware which allows you to modify master and slave mode at any time. HC-03 are industrial grade products, HC-05 are commercial grade products.
The modules with the HC-04 and HC-06 firmware are the modules which are factory set to be Master or Slave modules. Master and slave mode cannot be switched from the factory setting. HC-04 is an industrial grade product, HC-06 is a commercial grade product.
So, unless you know which module you have, master or slave, will probably determine what you can do with it.
From a hardware perspective, the HC-05 and HC-06 are identical, with different firmware. If you have the right tools, you can reprogram them.
