Hello,

With the Arduino IDE, I am able to upload my sketch with Bluetooth (see this)

Here is the output in the Arduino IDE's console:

But with Visual Micro, I get this error:

It looks like it can connect to the Bluetooth for like half a second, I see a led of my arduino blink 2-3 times, then Bluetooth disconnects and this error message appear.

Any idea why?

Please confirm which shield or board you are using. I'll get hold of the same one 

Thanks

Thanks I'll give it a try

Prior to upload both visual micro and arduino often (depending on the board config) open the port, set the dtr, wait a short time, flush the port, close the port and then run avrdude.

Visual Micro is written with windows .net. so uses the .net serial port functions.

Arduino is java based so doesn't use the .net framework serial port system instead it uses it's own native functions which access a low part of the windows api than .net

This difference can cause slight variations to the upload when timing is an issue. 

From your report I expect the opening of the port and closing it again, when using blue tooth, is causing the problem. Maybe the port needs more time to settle after open/close. 

I will also look into the vm options, if I recall there are some registry settings you can use to alter the delays but will have to look into it. Give me a few days, thanks. In the meantime you can switch on "file>preferences>external editor" in the arduino ide which allows you to code in vm then switch to arduino and click upload but that means no debugging.

Unfortunately its not that simple there is no read/write in what i described. I suspect if it is the issue it will be the time between the port.close and running avrdude.exe

I am busy on other project right now but will try it as soon as I can. 

You can use the verbose output from the upload attempt and make a .bat file that does the upload for you.

Something to try please. Just an experiment...

In arduinoide/hardware/arduino/avr you will find the boards.txt text file. please edit with notepad or texteditor and find the entry for the 2560 board you are using. It will look like this

mega2560.name=Arduino Mega 2560 or Mega ADK

mega2560.upload.protocol=wiring
mega2560.upload.maximum_size=253952
mega2560.upload.speed=115200
 

please add a command as follows then re-start the vm ide:-

mega2560.upload.disable_flushing=true 

I hope this makes sense.

Thanks

Hi,

Thanks very much for trying that. It cuts out quite a bit of processing and suggests my previous timing discussion is not valid.

It must be something simpler. Please try another test where you run the output from visual micro from a batch file (.bat).

C:\Program Files (x86)\Arduino\hardware\tools\avr\bin\avrdude "-CC:\Program Files (x86)\Arduino/hardware/tools/avr/etc/avrdude.conf" -v -v -v -v -patmega2560 -cwiring -PCOM13 -b115200 -D mega2560/multiserial.hex:i" 

Thanks for all the testing

Thanks, please try this boards.txt key

mega2560.upload.serial_ignore=true

ps: the quotes are not the issue, they were only required for the .bat. well spotted. sorry forgot to say run from arduino folder or copy cygwin.dll. That was an annoying change in the latest 1.5.7+ toolchains

Well I marked it as solved because this was solved indirectly in that other topic: http://www.visualmicro.com/forums/YaBB.pl?num=1417488083/8#8 . I should have linked to it here
