dfrduino romeo can't recognize an apc220
socrate_le_chat 2012-08-15 13:46:48 7681 Views8 Replies hello
I have bought a dfrduino romeo, v1.1, and an apc220. I am building an RC airplane.
I have some problems with the connection between the card and the PC when I use the apc220.
I made a program to arduino which send infinitely "abcd" to the serial port, it works perfectly with the USB wire. But with the apc220, the PC can't receive anything.
when the apc 220 is plugged in the apc220/Bluetooth socket the card can't recognize it (the LED tx and rx stay off).
thanks you.

I did the following :
sudo apt-get update
sudo apt-get distro-upgrade which asked a very long time
Then I rebooted and got the same null result for arduino
Is this upgrade what I had to do ? KavomatovlKiz

KavomatovlKiz 2012-08-18 10:47:57 I have had the APC220 for a while now on my DFRobotShop Rover, they don't work quite well. I was never able to make them work as Tranceivers, as in Transmit and Receive at the same time. Both units either work as TX or RX. Some other times, I have to keep recycling power on the DFRobotShop in order to make them start communicating with each other.
It's funny I saw your post. I just got into this website to find an alternative for the APC220. It's such a headache working with them. The only good part about it, is that it's low price.
Good luck. tonyawad88

thaks.
I think I have found a solution, I will use an other card connected to the PC with the USB and also connected with the romeo card on the plane with the apc220.
the serial tx and rx of the USB are connected to the pins tx and rx (it is the same serial connection) and I will use the card as a relay. socrate_le_chat

socrate_le_chat 2012-08-17 17:01:42 For Linux you would need the [url=https://www.dfrobot.com/index.php?route=product/product&path=45_82&product_id=104#.UC2Xqt3iazE]USB to TTL[/url] converter only. Not specifically for the APC. I'm not sure if it is available for Linux. Sorry.

I have make it run on windows, the communication works perfectly. but I am on GNU/Linux.
It is maybe a driver problem. I can't find the driver for the kernel 3.2 socrate_le_chat

Please connect both APC modules to the PC and make sure the configuration is correct. You can use the software provided on the product page.

Hector 2012-08-15 17:00:49 I can't receive or even emit with the apc220
how can I be sure that both apc have the same config ?
I have never connect the apc and also the USB. socrate_le_chat

socrate_le_chat 2012-08-15 16:22:21 Hi,
I'm not sure I understand. You mean when you plug in the APC module on the romeo and another on your pc you can not receive any info?
If so, have you made sure that both APC modules have the same config?
IF you mean that when the APC module is connected to the Romeo and ALSO the USB cable is connected, then this behavior is normal. The Romeo the same as all other Arduino (328p) has only 1 serial port and can only use 1 serial device at a time. When you connect anything else to the Tx/Rx pins (APC module uses these) then the USB communication is disabled.
