"Hallo I'm currently designing a board that fits a microhard n920 radio unit (just the nano unit neither the ip rev nor the full dev board) into a very small board with a level translator. If you still need it I can send you the project (i mean…"

Hey all, so I have a pair of APM2s that aren't working and I can't figure out why or how to fix them. I'll call them Alpha and Beta.Alpha will seemingly function when connected to a battery: lights…Continue

So I'm currently trying to fit a microhard n920 onto a Bixler, and unfortunately I don't see a way to do this without also having the dev board (doesn't look like they have a small breakout board I…Continue
Sniffing Mavlink packets

Hey all, I'm doing work with testing various radios for telemetry, and I was wondering if anyone had done work with sniffing and collecting the Mavlink packets for 3DR, XBee, microhard, Xtend, etc. …Continue

Dan G replied to Dan G's discussion APM2s Possibly Bricked"Well here's the conclusion I'm coming to based on more tests I've done...
With Alpha, if I hook up the 3DRs and go to the Terminal, I get a response from the APM if I spam it with Setup Radio, Tests, or Show Settings clicks, but to me…"
Denis replied to Dan G's discussion APM2s Possibly Bricked"I time my apm2 was bricked. I begin the initialization and then freeze. To solve this issues I do the following:
I arducopter code, in function init_ardupilot (file sytem.pde), just after the Serial port initialization…"

"Assuming you've also tried on another computer with another USB cable, and they're still not working, I'd contact customer support from the store you got them from and request a RMA."
Dan G replied to Dan G's discussion APM2s Possibly Bricked"Yeah it can't detect the version and says to check the cabling."

"With Alpha, have you tried reloading the firmware and erasing the eeprom (CLI setup/erase)?"
Dan G posted a discussionAPM2s Possibly Bricked
Hey all, so I have a pair of APM2s that aren't working and I can't figure out why or how to fix them. I'll call them Alpha and Beta.Alpha will seemingly function when connected to a battery: lights flash, GPS locks, RTF light comes on, etc. However, neither the USB nor the telemetry port work completely. The telemetry powers the radio but doesn't send or accept traffic, but that's not as important as USB. When I connect the USB, the APM powers up, the computer recognizes it as an APM, and I…See More
Dan G replied to Dan G's discussion Fitting a microhard on the Bixler"Not that I've seen, and this is a board-to-board type connector so theoretically the only thing you would be connecting the radio to is a board with this connector surface mounted on. I called them the other day and the best they could do…"
Jake Stew replied to Dan G's discussion Fitting a microhard on the Bixler"Wow! Is there no sort of cable or anything? You really don't want to be flying around with the whole dev board.
All you should really need for the radio is tx, rx, +3.3v, and ground lines. At some point this should essentially…"
Dan G replied to Dan G's discussion Fitting a microhard on the Bixler"Well the connector that is on the bottom of the radio is a AVX-Kyocera 5046 Series 60 pin, which I can't seem to find any sort of adapter for, and I don't feel like I can reliably solder to. There is a breakout board from microhard…"
Jake Stew replied to Dan G's discussion Fitting a microhard on the Bixler"You need to get a wired connector plug and put standard header pin connectors on one end. If you need TTL level conversion then use a cheap one from sparkfun.com
http://www.sparkfun.com/products/8745
It's $2.
What power in do you need…"
Dan G replied to Dan G's discussion Fitting a microhard on the Bixler"Well I don't have a way to wire in the voltage, ground, and RX/TX without it, and even if I do solder onto the tiny 60-pin connector I'm missing some sort of logic level conversion.
The whole dev kit was $900, don't know how much the…"
Jake Stew replied to Dan G's discussion Fitting a microhard on the Bixler"You need to put just the radio in there. Not the whole dev board!
How much do those cost BTW?"
Dan G posted a discussionFitting a microhard on the Bixler
So I'm currently trying to fit a microhard n920 onto a Bixler, and unfortunately I don't see a way to do this without also having the dev board (doesn't look like they have a small breakout board I can wire up to). I've managed to get it to fit into the fuselage, but don't see a way to connect the RS232 to the TTL converter. Anyone have a solution or know of some RS232 angle adapter that might work? Alternatively, is there a way to wire this using the RS485/422 pins?…See More
Michael Pursifull replied to Dan G's discussion Sniffing Mavlink packets"Sorry, I should have qualified, I was talking about Xbee. I thought that was understood since he mentioned spread spectrum rather than digital modulation. I was typing on my mobile. "
Jake Stew replied to Dan G's discussion Sniffing Mavlink packets"GFSK is what is implemented I think."
