The example sketches are difficult to follow and there is little in the way of help on the forums or the wider internet. I purchased a WiDo because of it's low price but I would recommend spending a little more and getting a more popular board, at least until more support is available.
Bluetooth 4.0, Actually the module communication distance depends a lot of things, the antenna, the environment, very complicated.
JaneYu ouch.. i need something better than esp8266 which can be use as AP..
check my project https://www.youtube.com/wat...
the smartphone connect to SSID on esp8266 coz it act as AP
JaneYu Hi!
The delay worked fine. Now I can see some text in the Serial Monitor. Thanks!
But...
It show just this:
========================
Hello, CC3000!
RX Buffer : 131 bytes
TX Buffer : 131 bytes
Free RAM: 1750
Initialising the CC3000 ...
========================
It doesn't go further in the code or at least it doesn't show anything else in the serial monitor...
Any help?
Thanks in advance.
JaneYu Hi. I'm trying to follow the first tutorial (Wiki). The sketch uploads ok to the board but nothing appears in the serial monitor. Any suggestion? Thanks!
JaneYu Since WIDO is using Leonardo chip, you can add a delay in the code setup(), to wait for the serial monitor open.
It couldn't be, wido is based on Leonardo Arduino board, Which pins are you using as Softwareserial port?
JaneYu The first method is certain OK. But I am not sure the second one, I am not sure whether the RDP data will disappear. Actually I recommend watchdog...
JaneYu Thanks, it's works. Using wdt_enable(*) and wdt_reset() make my program running continously.
Other problem, can I use 4k bytes(or less) to make program to save data in micro sd?
Thanks for your reply. As there are variable and parameter changes that need to be drastically checked, is dfrobot able to release an updated Adafruit library for the Wido that will work with Blynk?
JaneYu Working fine now, but follow one of the user Cain's idea, use IDE old version 1.0.6. But why ??
JaneYu I am sorry, the wifi chip doesn't support soft AP in this version. And you could select the accessories according to your project, like a IO shield.
JaneYu Problem solved! Managed to put it to work with the 1.0.6. Also had another problem, somehow the CC3000 was programed to work with static IP, I was able to change that with the "buildtest" after noticing that the IP was always the same (That was kind of strange...). Thank you.
JaneYu Please tell me how to use WiDo DFRobot with Dropbox or Google Drive. Thanks.
JaneYu Hello, I'm trying MQTT using this WiDo board. Can I use this?
JaneYu Hi, one of our client (Thailand) has made a project with WiDO+WRTnode, which is using MQTT protocol. You could take a look.
http://www.iotthai.com/%E0%... But this is Thai, I think you will need some help from google translate. ^_^ Anyway, what are you going to do with WiDO?
Great board for learners only!
Once you get more advanced the Leonardo memory limit (28K) is a huge limitation as CC3000 for wifi communications claims so much flash memory. For example I need OneWire, DallasTemperature, Serial (for LCD), and CC3000 + aREST + CC3000MDNS.
JaneYu The only good thing about the WiDo is how cheap it is, but like with most things, you get what you pay for. The WiDo has no support to help you with your project and it is extremely difficult to get the WiDo to work with any of the common IoT websites. In my opinion, as an owner of a WiDo, go for a different board. I could have saved myself a lot of time and frustration if I had.
JaneYu Please specify the problem you have, we may look into this together, documents of wido are available at http://www.dfrobot.com/wiki... .
Aha.I see.Is there any way I can do that? Is that a software issue or a hardware issue? Will Other wifi modules be restricted by the same issue? :s
JaneYu I couldn't agree more with. I also bought it as it was very cheap and now having problem with it as it has less support. But I think soon people will move towards WiDo as it is very cheap. So DFrobot should concentrate on supporting more with wifi codes and guides.
