"I got it working with the RF baud at 19200, and the serial baud at 57600. I think if you go and slower on the serial link side, it will be to slow for MAVLINK. The max on the RF side is 19200, but the max at the serial link side is 57600, which…"

"I can confirm the above link with the PDF at the bottom of post will set these up properly.   However I have a question hhaving the baud rate set wrong in APM, how do I set the baud rate in the APM code 2.21 to 19200.   Can this be done in…"

"Update info: http://www.rcgroups.com/forums/showpost.php?p=18523310&postcount=843 please try it."

"Hi Nosepo, unfortunately, also without the wireless module in the USB adapter, I get the same result. No COM ports are found by the app. I use the app linked in your RC groups post and windows 7."

"Serge, try this:     1.- Connect the usb serial converter without the wireless module.   2.- Open the APC app.   3.- try to selec the correct com, and try the rest ones which the app shows.   4.- When appear…"

"Hi Nosepo, thanks for your reply. I took a look at your post, but my problem starts at step 3. The APC program does not find any COM port. If i look in my device manager, COM4 is selected, but the dropdown list in the APC program is empty, also if I…"

"Hello Sarga.   Try this: http://www.rcgroups.com/forums/showpost.php?p=18523310&postcount=843   I'm trying to connect the APC220 modules from my Hexacopter to the APM without lucky. I tried to change the bauds, but i get…"

"Hey there.   I'm also using the APC220 modules for my APM. Thing is, they worked perfectly with the Ardupilot Legacy protocol, but with the new MAVLink, i think the default rate of 9600 Baud is too low (assumption from my side), because…"

"Hi Mark, Sorry for the delay- I hadn't searched on the apc220 for awhile. In my case, I have the same pins connected as you and am using HK GCS with success. Also, after signal is lost, it picks up the stream again without a hitch. The only…"

"hello is it still the same link or is another one ? if it's the same I get the same error... maybe will try it at the office on monday on a brand new iMac oh and I forgot ... thanks for your effort to bring a mac version  "

"tried to update to 10.6.6 but still impossible to launch it I have this error in terminal "Bad CPU type in executablelogout" I have this config :  Model Name:    MacBook Pro  Model Identifier:   …"

" not able to open the app :( running 10.6.2 on an intel macBookPro it says ArduCopter_MacGCS is not supported on this type of mac too bad ... any idea ?"

"Hi John,   Have you any other tips to get the APC220 working properly currently I have telem from ArduPiratesNG quad being sent to the configurator without an issue but any command I try to send from the configurator to the quad returns as…"

"This conversation is in a wrong place on the forum but anyway...   I too like the idea of cheap and available ESCs for an okto. I have built an okto with y-cables using quad electrics. You can check my…"

"Hi, Don't be discouraged- no extra code is necessary to use for configurator and telemetry. All you'll need to change code-wise is the user setting for baud rate so that it matches the APC220 (you'll likely use 19200)."

"Oops I didn't find this thread sorry ! ok thanks a lot ! Seems better to go with the xbee if I'm not experimented in writing code :) it looks it work so easy with other arduino boards ..."
