Hello,I've read many threads these past days and before giving up I'll give it another shot...Here's the deal- I bought the Neo-6m from HK, connected to the Crius board and got NO GPS.Trying to…Continue
"OK, so maybe it was a coincidence that it started working when I switched to a new UBEC. Today it wouldn't boot and I took a look at the board since I had been flying in a dusty/leafy spot yesterday. I brushed off what I thought was a clump of…"
"I'm feeling like I want to start looking at the code (not like I feel like I'm going to understand it very well) to see what it's trying to do on bootup. It seems like there's some sort of hiccup going on here that's more of…"
"That's about what it was doing for me. There were two orange RX/TX LED's by the USB connector that would alternately flash and the red LED would flash a few times and that was about all that would happen.
I'm only speculating here so please excuse me... When I tried to work the problem I tried to eliminate the smallest details that may be overlooked, like wires, for example. Bad wiring may cause this issue (perhaps you're using one…"
I have another issue with the CRIUS board, maybe you could help: if I connect the battery, the board flashes twice but does not boot (both UBEC or ESC power), however if I connect the USB first then it boots and stays on after connecting the…"
"Ive got the same Issue, I only get a GPS lock on USB, and not on 3S battery. Ive left it on battery for 30mins and no lock, just flashes. Connect it to USB and in under 60 seconds i have a 3d fix.
This has happened with 2 GPS units now
I have the V. 2 board, but as I mentioned the GPS has been receiving power (the LED came on), and the U-Center was able to initialize a connection (but no data), so that wasn't the issue. Last night I finally got an answer from HK stating…"
"Did you get your CRIUS board from Hobby King as well? They had a problem with the voltage regulator on the boards they had made. They released a "Version 2" that fixed the problem. I'm trying to remember specifically what the issue…"
Thanks for your posts and I'm glad it worked out for you. I have tried the connecting the GPS to the laptop with USB and FTDI board, to no avail. Upon contacting HK regarding this issue, I have been getting very sketchy answers about…"
"Solved it. My UBEC wasn't supplying enough power. The GPS wasn't the problem but the tipping point where the whole system browned out. I discovered this by connecting the board to the laptop with the USB cable. Booted right up . . . but…"
"On the CRIUS I need to connect bare ends from the connecter attached to the GPS to the bare ends going into Serial2? on the AIOP. I had started with a Dupont connecter, but I ended up soldering each connection after the perceived loose connection…"
"I have a NEO-6M running on a CRIUS AIOP. Something is weird where the GPS seems to keep the whole system from booting up. if I unplug the GPS it will boot up fine. Maybe there's still a loose or intermittent connection, but I have my suspicions…"
