Bluetooth interface for STAG 4 or QBOX gas installation
Hello everyone, I was inspired by another thread on the electrode related to the 232 interface for the gas installation.
I made the interface presented here over 2 years ago, in the meantime, about a week, new versions were created. The final version was quite universal. It can be reprogrammed to STAG 4 or QBOX by bringing the magnet closer.
I used the STAG plug, the HC-05 bluetooth module, the 7805 stabilizer (or the step-down converter set to 4.9V), the reed switch which has contacts for reprogramming the settings, universal remote control housing, hot glue, heat shrink tubing.
Thanks to this interface, I corrected settings and updated drivers in my and other vehicles.
I wanted it to be small, handy, durable and that's what it is.
Photo of the first version:
And the final one after all modifications:
And the end result:
The original one at the moment is about PLN 80
but over 2 years ago it was not so colorful.
Any laptop with bluetooth was enough to work, and the 232 port and cable tethering were a thing of the past.
Each intervention in the controller is recorded / saved in it (in the controller).
The installer, if he hooks up and programmed on the same computer, will pop up a message that he was programmed with a different computer.
It was not like that in my case.
In the STAG QBOX controller it communicates with the Android phone application (parameter preview)

"interference" - that is, the readings are recorded, doesn't it count? Was there a lot of combining with the HC-05 configuration? [Read more]
How is communication with these two drivers different? What is this reed switch for? [Read more]
Just connecting to the driver, if I remember correctly (over 2 years ago it was) A banal configuration, a USB programming cable that saves disks from TX, RX and GND. I will add 3 more photos because... [Read more]
Each connection to the controller is saved. I don't remember which and which company the new drivers have a connection counter, after which they are "full", they are blocked and need to be replaced... [Read more]
If there are such drivers, a colleague could mention their names, what companies / models they are, because STAG does not protect its devices in this way, and that's why I always choose STAG, because... [Read more]
Were there attempts to connect with other drivers, e.g. Lovato? [Read more]
Not only STAG 4 and after reprogramming STAG QBOX I tried with Zenit, despite supplying external power after the first attempt, I gave up due to lack of time. [Read more]
So the hc-05 module fits right out of the box? I do not need to change anything? You only entered the password and name, but it is not essential for the connection between the module and the stag, and... [Read more]
Hello. I will present you my battles with a similar topic. A year ago, I glued something similar to the STAG-300 ISA2, but due to my inattention, I released my HC and probably the communication inputs... [Read more]
I programmed the HC-05 as above 3 print screens - 9600 for stag 4 (I had the eco version) Well, it makes no sense to pour the whole glue. I will tell you that the versions with the 7805 stabilizer, despite... [Read more]
Hello, great idea, I have the elements in a drawer, I will try to replace the wired interface with this one, we will see how it works. I didn't think it was that simple. :D [Read more]

At 100%, the speed of communication is higher, but I do not remember how much than in stag 4 [Read more]
Can the communication speed be "previewed" on the wired internet connection to GO-FAST, because I have one, and I wanted BT? Are they unrelated? [Read more]
I have no idea what it's like with a wired one, I've never had one [Read more]

-> Arek1984 Very helpful link, everything is thanks. :D [Read more]
Hello, it took a while, but it worked. My HC-05 module failed to reprogram with Arduino, I don't know why. :D I had to order from Ali .. TTL UART converter, by the way I ordered a small 5V pulse... [Read more]
I would stick to the casing because it looks delicate, but it is important that it works and there is POWER; D [Read more]
