VemsTune for Android ?

[fphil]

BTW Do you know if there is a chance to interface VT on Android through the usb port of a (cheap) TabletPC,

[VEMS]

Vems BT adapters are specially tailored to use a low latency BT connection, we do not recommend using any other than the adapter available in the webshop ( https://shop.vems.hu/catalog/bluetooth-rs232-adapter-p-179.html).

Using VemsDisplay over USB is not supported.

Using VemsDisplay over USB is not supported.

Too bad the price of some 7" TabletPC+android is now 49Euro which is the price of a Bluetooth-RS232 adapter and which is cheaper than a blue LCD...
Price and techno has changed a lot these last 5 years

Hello Phil,

If this option is feasible, adding support for it should not be to hard at all (at the VemsDisplay application side). I suspect the challenge lies on the Android side, finding an usb2serial (FTDI based), that connects to (and has device drivers for) Android. If you have some examples, we could investigate.

Best regards, Dave

Can some of this be used to connect android to r
Ftdi usb to seriel

I followed the links given by mads b (dk).

If I am not wrong, a new FT312D chip has been developed by FTDI which allows the automatic call of the Open Accessory Mode of the Android device, hence no drivers are needed. This chip has been integrated into some Android to USB cable (eg. DIGITUS DA-70160 :: DIGITUS® Android <> RS232 cable 18 Euros).
FTDI site also explains how to modify or complete the android kernel in order to support their other chips.

PS just got my WETAB704B (49E) from the hyperstore, ready for DIGITUS +VT USB Android

Resurrecting this thread.

I have bought a BT adapter from webshop and it works well, though with cheap HC-06 modules from ebay (with voltage regulator board and pins already in place) I cannot establish a connection. Pairs nicely with tablet, but no data from VEMS. Also cannot connect via terminal to change baud rates (default is 9600). Tried swapping Rx and Tx, still nothing.

I am aware of the short timeframe for sending commands but pasting also does not work. Any hints?

Module is typical arduino unit:

You must use capital letters to get the commands to work..... use ispi connector to connect hc-06 to vems at ttl level
Edit: The default pairing code is 1234:

[PeepPaadam]

Yes, that is how I did, with capital letters.

But do you have any schematics how to connect it to ISP?

[mads b (dk)]

This i how mine is connected on ISPI

ISPI       HC-06
ben 1 = TX
ben 2 = 5volt vcc
ben 4 = RX
ben 6 = GND

Is there still a problem with the EGT temp or is there a update available?

Hi, one good new. I've tried VemsDisplay on cheap 10" tablet with MTK MT8127 (quad core) tablet, 4.4.2 KiteKat and Bluetooth 4.0 + HC06 module and it works.... But devices with older MTK chipset doesn't work still (see my older post) - tested on VemsDisplay 2014-07-15.

[PeepPaadam]

Did you change the baud rate to 19200 also on the HC-06? Does it work when HC-06 has default baud rate 9600?

[mads b (dk)]

Baud Changed to 19200 on HC-06

[Pet]

Of course, you have to change baudrate on HC-06 :
 19200  - "AT+BAUD5"
115200 - "AT+BAUD8"
