Wifi supports US region only #39

Closed vk7hse closed 8 years ago

vk7hse commented 8 years ago

WICED Feather currently only supports 2.4GHz wifi CH1 through CH11

My understanding is that the Broadcom chip is currently locked to the US 2.4GHz band plan so to keep it within the US regulation.

(I did a quick check on the 2.4GHz wifi band and noticed that for the USA CH12 and CH13 are not permitted)

Thanks for the information, but since this isn't a bug with the library itself, but rather a piece of information about WICED, I'm going to close this issue.

astra1963 commented 8 years ago

Is it really true that european and japanese channels are locked by hardware? I can´t see something like this on the layout and the WICED module is sold worldwide so there should be no limitations from this side.

microbuilder commented 8 years ago

Channels 1 to 11 are perfectly fine in Europe as well, see https://en.wikipedia.org/wiki/List_of_WLAN_channels#Interference_concerns

astra1963 commented 8 years ago

I know but there are APs I don´t have access to the channel choice that work on ch11 and 12. It would really be great to have the possibility to access them.

microbuilder commented 8 years ago

We'll look into whether these can be enabled as a command in FeatherLib, or whether this would require a separate FeatherLib build. It's a SW not a HW limitation, but we'll need to explore how to handle this in a way that's easy to maintain.

vk7hse commented 8 years ago

Noticed some new comments with regards to the upper channels, Although I raised this back in March, it was more to just make it known and so that people didn't RMA the device thinking it's faulty. Easiest way to resolve would be make mention in the learning/documentation for the WICED. ;)

hathach commented 8 years ago

We just push a new code in development branch that probably resolve this. You can get/set the WiFi country using these constant (a featherlib upgrade is required).

https://github.com/adafruit/Adafruit_WICED_Arduino/blob/development/cores/maple/libmaple/adafruit_constants.h#L285

Set command will save the country code to nvm, it will last through power lost or reset. Check out the new example here

https://github.com/adafruit/Adafruit_WICED_Arduino/blob/development/libraries/AdafruitWicedExamples/WiFi/WifiCountry/WifiCountry.ino

We haven't tested if the set command could change the country on-the-fly or it needs to go through a reset cycle. Could you mind helping us to confirm this when connecting to your AP.

vk7hse commented 8 years ago

Due to it being almost 3am (don't ask why I'm watching Netflix!) I'll run tests later in the morning and report back.

vk7hse commented 8 years ago

Initial test of setting the region to Australia came back stating that the changes had been made. I then changed my router to CH13 and let the WICED do an AP scan (the one in wifi/examples however my router wasn't seen so I set to CH12 and again no show, next was CH11 and it displayed as expected.

More testing to be done, I don't have any equipment to be able to view debugging direct from the chip, so I'll obviously need to find a way to get more verbose output the see what is happening with the setting once changed.

More to come...

astra1963 commented 8 years ago

Sorry that it took me so long to test. Tested it for Germany and it does exactly what expected. Works fine with channels 12, 13 and all others.

Thank you guys

astra1963 commented 8 years ago

With WLAN_COUNTRY = WIFI_COUNTRY_AUSTRALIA it works fine with 12 and 13, too

microbuilder commented 8 years ago

Thanks, we'll include this as part of the next release (0.6.2).

hathach commented 8 years ago

@vk7hse could you get it work with further testing. @astra1963 already confirmed that it worked with AU country.

vk7hse commented 8 years ago

I haven't as yet, but I was going to grab a clean copy of the firmware update from github, as I don't think the 0.62 was truly at that stage, I think I'd messed up my local copy, I should get a chance to in the next day to confirm, to be honest I don't really have an issue with the upper channels not being available, as I've populated lower down! However I'll get back to you with my findings as soon as humanly possible! (read that as when I'm not playing Mr Mum!)

So once I let this run the country was changed to AU

I setup a router on ch13 and used the ScanNetworks sketch and I wasn't able to receive it. Next I uploaded SoftAP Client RSSI Example set it to use ch13 and it failed to set the channel

I've got both the BATADC and SPIFCS bridged although I don't imagine they would have any impact on this.

hathach commented 8 years ago

thanks for the feedback, we will double check it again.

vk7hse commented 8 years ago

Further to this I attempted setting to Germany just to see if that made any difference, but nope! 😟

Unfortunately I don't have any debugging equipment that can interrogate to get what's happening within the mcu, I'm saving to buy the SEGGER J-Link EDU - JTAG/SWD Debugger as I'm wanting to learn more about the inner workings of this kind of stuff! I've been dropping hints to the family for Xmas! 😉

@vk7hse thanks, we will double check later, got into middle of high speed ADC issue :D . You should also list Saleae Logic to the list as well :grin:

astra1963 commented 8 years ago

Do you need any data from my working environment? Can I give some assistance?

hathach commented 8 years ago

@astra1963 Sorry for late response, just stuck with other issues. Since it works well for you, I think it is fine. Since we are late on the release schedule, we will release as it is and come back later if others encounter the issue as @vk7hse .

vk7hse commented 8 years ago

Sounds like a plan!

Just out of curiosity though, is it possible that because I've got both of the optional jumper pads bridged that might be a problem? I don't think that it is, but just wondering if it's worth removing them and re-rest? Thoughts?

The solder jumpers don't matter here ... one enables SPI flash and the other enables monitoring the LIPO battery voltage through a voltage divider.
