This is the antenna I have used:
It seems to work fine and it's designed to work with the Quectel EC25 used on the Omega2 LTE. I cannot attest to it's its long term quality as I've only used it for some POC testing. But for the price it's hard to go wrong.
Small note here, MIPI CSI-2 can also use more [than two] lanes (it's basically the same interface, and I believe uses I2C to control/setup the sensor). This is offered with newer 22-pin connector based camera sensors for other solutions - I may need to dig into their schematics + source a bit to understand which pins on their chips they use, but there is an assumption here that they have the support for the interface built in.
@Flosol The EC-RED certification for the Omega2S & Omega2S+ has been updated with the latest versions of the standards.
Find the updated certificate here: https://github.com/OnionIoT/Omega2/blob/master/Documents/Certification/Omega2S/Omega2S EC-RED Certificate.pdf
And the corresponding test reports here:
Certification updates for the Omega2 & Omega2+ are in progress.
@altr I'm not sure about OpenWrt 21, but check out this wiki about how to control the LED via a trigger.
I know it works as it is one of the earlier things I tried when learning about the Omega2.
Why don't you just read the (pseudo) file? No need to open new processes. Using
w = int(open('/sys/class/leds/omega2lte:blue:wifi/brightness').read())
Will give you what you need from python in a pythonic way.
@BeekyB My first suggestion is to ensure you have your Omega2 powered up.
Or you could provide more details of what problem you are experiencing so perhaps members of the community may have some ideas of how to solve whatever issue you are experiencing.
@phzdw Onion published the code to their python gpio module. Open source providers like Onion release their code so developers can collaborate on improvements and updates. This model allows companies such as Onion to push forward on new products rather than be tied down maintaining older code. This is the basic principle of the commercial open source model.
@MarshalllGG Yes you can compile on say Linux but you have to run the app on your Omega2. Sometimes if I am developing an app I might do the skeleton of the work on my Linux system and test it on Linux without all the Omega2 specific stuff. Once I have that all correct I then start adding the Omega2 specific stuff and then need to test it on the Omega2.
Hello and thank you for your reply, So yes I have the dock but don't want to use the USB micro socket to power the onion. What I want to do is design a board that mounts on the 30 pin expansion socket to give me access to other things like 12c, SPI ect. but also want to have a 24VDC to 5 VDC supply on this board and want to feed the 5VDC into the expansion socket if this is possible?
After having the auto-provisioning up and running I still have a small imperfection in play.
Whenever mtd -r write <IMAGE-NAME>.bin firmware finishes it does not do the -r because it complains about not being able to [e]rase a block. ...it exits with 1
Writing from 20211027-pan35-blusser-9-5.bin to firmware ...
[e]Failed to erase block
mtd verify doesn't end well either.
After a reboot the omega seems to be running my custom firmware happily, so I dont worry too much yet, but it keeps nagging
I have followed the instructions closely, also tried a couple of times more to make a new .bin file using the dd method.
This is how that runs:
root@Pandora3-74F3:/mnt/mmcblk0# dd if=/dev/mtd3 of=20211108-pan35-blusser-9-5.bin
64896+0 records in
64896+0 records out
Any idea where i should look?
Same question to remove WiFi came in from our customer support department. We know we can disable the WiFi from software, but the customer has the specific security requirement that there should be no physical WiFi possible.
I'm sorry to hear that removing the 0 Ohm resistor and the ceramic antenna isn't enough to disable the WiFi. Are there other hardware changes we can make to permanently disable (break) the WiFi on the Omega2+?
Hi @crispyoz , I didn't need to modify the package, because I misunderstood the error at the beginning. Now I solved the problem after long hours. I managed to program using swd mode, it was actually available but the error message was misleading for me. Thanks a lot though
