Hi guys,
I just tried the latest update of ACM and it seemed to work with both xbee (I have 2X 2.4Ghz 60mw pro modules) and usb - I can get telemetry and use MavLink via xbee etc.
I did have problems like yours before though with trying to communicate with xbee's so I powered my board with an esc and put an N4001 diode in series with the esc line coming into APM. I also added this stuff to my config file:
#define MAG_ORIENTATION AP_COMPASS_COMPONENTS_DOWN_PINS_FORWARD
#define GCS_PROTOCOL GCS_PROTOCOL_MAVLINK /*GCS_PROTOCOL_LEGACY OR GCS_PROTOCOL_MAVLINK*/
#define GCS_PORT 3
#define SERIAL3_BAUD 57600
This seemed to work for me with my gps, magnometer all plugged in as well. I also reset the board and erase the EEPROM every time I upload new code, as I have had a few strange things happen when I don't.
Hi Jerry,
I work up at 90th and Mountain View just off the 101 and Shea. Would you be up for lending me your quad (or just the electronics) over the weekend? I know you've been at this for awhile, but getting another head on the case first-hand couldn't hurt. Let me know and we can meet up tomorrow.
For anyone still having trouble connecting via Xbee, please ensure that you're powering APM with an ESC/Lipo, not just USB. USB power is not enough for both APM and an Xbee. (You can sometimes tell that you're browning out because you just get the red C LED blinking dimly and slowly.)
Jerry, to where you have send your queries? As we have not seen your name on our email lists. Please use contact us on jDrones page to make sure that your queries are saved and tracked properly. If you send private emails etc they are getting lost due there is rather heavy traffic on our private email boxes.
Project status is always on the News page on the project Google Code home page, with the manual.
In tje meantime I really recommend that you contact jdrones tech support and get them to walk you through the setup. That's what they're there for!
I've finally got things working with GCS/Mavlink/AC2. It is possible that my problems were unique to me, but maybe it will help someone.
First of all, my reset sequence was hanging at the Barometric Pressure Sensor initialization (thanks for the tip Michael). I then saw that it only happened if I had the GPS unit connected. If I disconnected the GPS unit, the BMP085 would initialize and MAVlink would connect etc.
I then updated the MediaTek GPS with the latest firmware (1.6). With that update, the reset process didn't hang when initializing the Pressure sensor, MAVlink connected and now everything is working together (GCS/sensor-view/planner).
So, in summary, my problem was that I didn't have the latest firmware on the MediaTek GPS.
