romeo board is now not being recognised my pc via usb- DFRobot Forum

2011-06-11 10:23:41 hi admin, i board is being sent back so should have a replacement soon, in the mean time i have bought another romeo board to hopefully get the apc220 rf modules working

[i]void setup()
{
//Air Rate should be set according to the APC220 Modules
Serial.begin(9600);
}
void loop()
{
Serial.print("Hello!");
//Arduino side transmit once every 500msï¼Œreceived by APC220 side
Serial.println(" My Robot");
delay(500);
}[/i]

this is the code uploaded to board and responds via usb connection but does not when using the modules, , i thought the romeo board was simply swap round the usb for the apc220 and then change com port on pc side?

my aim is to use these modules to move the robot from the ide com port from pc if thats possible with these transmitters?
if you are able to help with this issue to i would be very grateful too,

2011-06-09 05:41:58 hey admin, i received an email today from the supplier, said they where out of stock and will be placing and order with you, the annoying thing is that ive been told to send the mcu to their technical department, which is in Portugal, which means postage is probably going to be expensive. bkrause

2011-06-05 19:19:59 thanks again for your reply,

the romeo board was bought from a reseller in the united kingdom and not actually bought via this site, mainly because i cant afford the import fee.
should i pursue this with the seller used?

thanks for your time bkrause

2011-06-05 17:54:36 Hi, it could be a faulty romeo. Please send it back and we will replace you a new one. R2D2C3PO

2011-06-05 08:02:28 hi admin thanks for your reply,

i should have said that the apc220 modules has been disconnected in attempts to get the mcu recognized.

i have also swapped out the usb cables, the 3 that i have dont make any difference nor does switching to another usb port, the strange thing is that when the "pc side" usb/ttl converter +apc220 is connected via usb port the pc sees it immediately. with that and that the cables where pulled from working devices(printers) and that usb ports do work on pc, brings it back to the usb port on the mcu, which holding the cable in at different angles doesnt spark any life either on pc end unfortunately.yet the pwr light also ways comes one when plugged in. im at a total loss.

also to do add, powering the board externally is done by the gnd to the blue gnd screw socket of the romeo, yet the dfrobot is connected to the vin=m jumper next to the blue screw sockets , as its never powered via two cables screwed in..
also my failed communication attempts which modules that are both picked by computer and seem to work, but not with simple code, followed this
[url=http://www.emartee.com/product/41855/] http://www.emartee.com/product/41855/[/url] yet nothing worked, the romeo i thought you just had to plug the apc220 in and its ready to go with that above code,

could these problems be an indication of a faulty board? bkrause

2011-06-04 23:54:38 Remove APC220 modules and try to hold the usb cable of romeo side to see whether it has anything to change.

Another thing to try is to use another usb cable and of course any usb port.

Let me know if you have tried these and any results.

2011-06-04 16:26:33 Hello..this is probably my first post ever..lol.

i have a romeo board v1.0 (2010 i think) recently bought around two week ago now, my pc recognized the board and wen driver was installed it all was working ok, but a few hours ago after uploading a sketch to try and communicate via the APC220 module (very unsuccessful) it is no no longer regonised by my computer.

the mcu usb port when the cable is in, is very loose now, but the mcu still power on (red pwr light on) and the "L" led flashes on, yet nothing from pc end. i removed the driver on my laptop and reinstalled it and that hasnt made it seen. this is very annoying and dam depressing as nothing i have actually done has worked properly in regards to this robot, so please if there is any one who can help,shed some light on this pc not recognizing mcu problem i would be very thankful.

thanks for your time.. bkrause
