MemberLook at the contents of https://github.com/synthetos/TinyG/blob/master/firmware/tinyg/settings/
MemberSo $$ isn’t the full parameter list?
Needs further investigation…
MemberWouldn’t you be better off using a driver, rather than a controller?
MemberIt doesn’t output 6V, it needs 6V to work. Dividing the voltage would render it inoperable.
MemberThe Bay’s no good for me – they usually won’t ship to these parts, but thanks. It’s enough for me to find something.
MemberI am wandering why I cannot use HC-06 ?
I’m 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.
MemberWas I incorrect in assuming that your Arduino reference was an Arduino Uno?
Yes, I use mostly Nano’s, Pro Micro’s.
The ‘Uno setup suite’ is the Arduino IDE – same for all models of Arduino. I didn’t bother going into detail on how you communicate with the Arduino, because if you have one, you invariably know how to talk to/program it.
So once paired, Coolterm on your PC can send the “AT+UART=230400,0,0″ over the BT link to the far end HC-05. Cool.
No, the only way to get into command mode is by setting P34 high, via the Arduino and some sort of USB-attached serial connection. The SPP (Serial Port Profile) devices are really dumb. You can go into command mode and tell them how they are to be configured and then reboot them in either master or slave mode and use them as a wireless serial device. You can’t make a BT session and go into command mode. They aren’t flexible like a general-purpose Bluetooth device, even though they have the same chip. It’s all in the firmware and how the pins are broken out. These are aimed at a single purpose. You could rewrite/reflash the firmware and get other functions (like audio, etc.) if you wanted, but the HC-series modules are all aimed at serial comms.
MemberExcellent!
Member“I’ll also assume that to make changes, such as your follow-on change to 230400 baud rate, one needs to go back to the Uno setup suite.”
I don’t know what a ‘Uno setup suite’ is, so I doubt I used one 🙂
I changed the parameter using CoolTerm, then rebooted and changed the default baud rate on my CoolTerm settings.
Chilipeppr and tgFX both worked fine with the BT device – but I am on a Mac. My ‘production’ machine is an HP laptop running Win8.1. I will try it out on there nd let you know. I have been using the Mac a lot lately as it has all my other stuff on it – and that was the impetus to add BT to the TinyG – I didn’t want to have to keep connecting and unplugging the Mac.
MemberI’m not sure what you mean by ‘tokens’, but wouldn’t the $$ command give you all the parameters available?
MemberI would love to see how you installed your ferrite beads, Mort.
Also, you said “The fix is to install a EMI filter in the mains power line very close to the VFD”
Can you expand on that? What is an EMI filter and how would I install one?
MemberThanks Alden
MemberYou can add an external driver pretty easily. Wire it to the external connectors on the TinyG board.
You should be able to buy something in Australia easily enough without having to send it back to .
If you want the same – a Ti DRV8825 – you can get a ‘Polulu’ type external driver: http://www.robotgear.com.au/Product.aspx/Details/707-DRV8825-Stepper-Motor-Driver-Carrier-High-Current-V2
MemberBoth my TinyGs are the same – bought at the same time – I was just mucking around after I put the BT module on and thought I would see whether I could do maintenance under BT – like upgrading firmware, etc.
As far as I am aware, nothing I have tried to date has resulted in an error.
The point I was making was that the Wiki says to not use the edge branch for production, but the shipping units have the edge branch loaded. Either the wiki needs a better explanation or the shipping units should ship with ‘production’ code.
I imagine I am not alone in not checking the isntalled version vs releases right off.
It’s not a criticism, it was meant as a question because the wiki is clear that you are inviting armageddon should you use the edge branch 😉
MemberDetails details 🙂 Of course – thanks.
At some stage you will need to connect your BT module to your TinyG.:)
