I have been using the 915mhz telemetry v2 units with my Pixhawk for a while now. One of them is not giving the range that it used to and I need a replacement.
I varified the range with the use of my Fighting Walrus iDrone Link and one unit is getting about 100m range while the other is getting good signal to where my hexacopter is just a spec in the distance.
I can not get hold of Fighting Walrus any more. They have not answered my emails since about October of 2015. I am assuming they are no longer active? (also no updates to their iOS app for almost a year)
3DR are no longer making their 900 or 433 telemetry units. (verified vie an email to them)
Thank you for contacting 3DRobotics customer service.
We apologize for the inconvenience. Unfortunately, we do not have the Telemetry available anymore since they have been discontinued, both the 915 and 433."
I am using a Nexus 7 v2 Tablet with the Tower App (great app by the way)
Other than the $250 long range 900mhz kits (I don't need/am not allowed to use super long range) or $10 knock 3DR off kits from China (gamble as to whether you get a good one/no warranty), what options are there that are "PnP" ?
I am using a Taranis Plus TX with x8r RX and could use that telemetry but then there is no way to load missions in the field.
Thanks for input
Have you considered using a bluetooth link to your tablet to load missions, and use the frsky telemetry to check yoru battery status'
try this, you may just need to tune the radios http://diydrones.com/profiles/blogs/915-mhz-3dr-radio-tuning-with-7...
Thanks for your input. I have toyed with the idea. I guess I should check into how much data the Taranis will actually give me. I like to have Amps, Volt and altitude as a minimum. I already have timers set on the Taranis.
Can you give me a starting pointer to a BT link that works directly with the Pixhawk?
This one or is there a "better link"? http://copter.ardupilot.com/wiki/common-mission-planner-bluetooth-c...
Something that my Nexus 7 will connect to easily?
Thanks mate for the link. That looks a little over my head and by the looks, I will need a spectrum analyzer to do the tuning. Am I reading the post correctly?
You do need a Spectrum Analyzer, but that is done using a 'Software Defined Radio' module you can get ~$10 see http://www.ebay.ca/itm/NEW-USB-DVB-T-RTL-SDR-Realtek-RTL2832U-R820T... as example.
You install the FW supplied in the post, tune the radios to be a matched pair. The setting is saved permanently, then reinstall the standard FW and you are good to go.
You can also turn the SDR module into a desktop ADS-B receiver when you are done
I actually use mine to listen to the FM Radio ;)
my I suggest http://store.rfdesign.com.au/radio-modem-bundles/, they have excellent products and as bonus 4 u they also are in the land of oz / under down.......
they are also compatible with 3dr radios
I used to work with 3DR telemetry exclusively, in addition to Taranis / D8R or D4R. Recently I get a telemetry set from Drotek for half the price. Chinese stuff but working well (with correct Sanders and Rmilec antennas).
More recently I tried the Ultimate LRS set up, with two Orange module (low price, one inside Taranis and other inside plane) and a bit of soldering I have one single 433 system for both RC and Mavlink telemetry. So far I am a bit amazed by the saving and performances. The full spread should cost you around 50€. It is said to work a few 10 km, with the good antennas, as always.
Has anyone else noticed that it is getting harder and harder to order do it yourself drone parts from 3DR? The 3DR web site is actually making it hard to order a collection of autopilot parts for an autopilot.
The 3DR web site used to make it easy to select an autopilot, GPS, radio, power monitor, etc. I suspect that it has become so hard to order do it yourself autopilot parts that people are going elsewhere. I cannot imagine what 3DR is thinking to discontinue the 3DR radios. They were even pretty competitively priced.
3DR is changing from a DIY shop to a consumer shop like DJI.
Nevertheless now there are many shops were you can get all and more of what 3DR use to sell.
I have heard rumors last year that 3DR are going to change from a DIY shop to something similar to DJI, but it looks like those rumors were true.
I feel like a Mushroom....being kept in the dark and fed sh.t!
The 3DR radios were open sourced to encourage other manufacturers to make them, which worked great. They're now available from many sources at even lower prices. I like the HK version myself.
As Francisco rightly pointed out we announced we were focusing on high-volume RTF consumer and enterprise drones (rather than low-volume DIY parts) last year. Very much part of our public strategy and the way the rest of the industry leaders are going, too. There are tons of DIY and hobby parts manufacturers out there, and the consumer choice has never been better. Open source works!
