I am facing various problems with I2C.
I can communicate with an OLED (send)
Then I tried using an ADS1115 (4 analog inputs)
I can not get correct readings
Always returns 0xff
I also tried to communicate with a NodeMCU without success.
The i2cdetect command does not work, it always returns the same thing, no matter what is connected and not connected.

In addition to other problems with interruptions and other details in Omega2.
To make a simple button, I have to do a loop that consumes a lot of processing.

Another detail is that I can not communicate with onion.io, since I made the freight payment spent more than two months to get a response on the screening.
Imagine support, if I send a message only next year I'll have something.

This way it is impossible to have a confidence in the company in acquiring a large amount of Omega2S.
I am in tests to be able to homologate the product to be able to make a purchase of at least 1000 omega.

I have a deadline to build the product if I do not lose the investment and I can not get a simple answer.

Even an email requesting a estimate of 1000 omega2s was not answered.

How they want us to rely on buying the Omega2S would be for OEM without serious support. Efforts will once again be made to resolve the problems.
Without proper support, fixes of problems, it is impossible to trust and acquire more products.

Do not tell me I had great plans. Giant purchases to mass produce. But I paused for defects. They wanted to plug the hole launching with the Arduino (SPI, I2C ...).

It seems to me that they are launching products to enable the company to sustain itself, forgetting the quality.

Q4 2017 at the end and we have no resolution of Wifi and SPI and the company is worrying about launching more products with defects than solving the problems.

I agree.
If it is a defect of the MT7680, should not the defect have been detected when developing hardware and disclosing that it has SPI support?

Place in the list:
WIFI Driver.
Prediction Q3 2017.
Until now, nothing.

Interruptions
You can use it by installing custom firmware or by compiling gpio-irq.
Official support: no
No company response

As in other topics, I have also opened a complaint even from the support and the sales part, that I requested a quote and that was never answered.

It is unfortunate to have a product launched with various problems and no company responses. And more than 8 months without a software update.

And their idea is:
Does not work on omega2, puts an arduino, makes the communication via serial and ready. Problem solved.
I2S, ADC, Interruption, DHT22, ADS1115, etc ...

I managed to reproduce the firmware almost the same as the omega, same packages. Only in newer versions and with Wifi (package) without kernel panic occur. But I can not start the wifi.

I'm using the Omega drive but I can not start it.

When running the wifi command:

We're in the same boat.
And I have other problems like i2c, support of the company, part of sales that neither answers.

@Chris-Drake I've tried it too.

It's been a disappointment to work with Omega2.
I thought it would be one of the best experiences but it is being exhausting.
I do not have answers by email.
Estimate requests are not answered.
Firmware already has months without an update.
I can not create custom firmware because the actual version that is generated is not available.
