OK so firstly what do you want to send to the phone. Are you sending a SMS or do you want to send data and have an application on the phone read that and then do something with it.

Is you phone Apple 4S or newer, if so then you can go down the BLE route if it is another phone the perhaps classic Bluetooth pairing your phone to the umbrella may be the way to go.

Cheers Pete.

Bainesbunch & robtillaart & PeterH, you are almost agree on the approach of first turning the power to the WIFI shield off (with one transistor circuit switched or whatever) and then putting the Arduino into sleep mode (and later resume it from RTC or so).

I think you are overlooking the fact that even in sleep mode the standard Arduino boards have a considerable power consumption. If you want to drop the overall current draw to almost nothing you need to provide a way to disconnect power to the Arduino as well. Obviously, reconnecting it afterwards is the trick.

If you use a standalone Arduino or a clone designed for minimal power consumption then you don't have that problem and can leave the Arduino powered up in sleep mode.

Yes hence my suggestion of a 555 timer to cut the power to the Arduino and then after nnn time reconnect it. the timer being triggered by the Arduino. That way the only thing drawing power is the 555.

Cheers Pete.

First, thanks for your answers.

Bainesbunch & robtillaart & PeterH, you are almost agree on the approach of first turning the power to the WIFI shield off (with one transistor circuit switched or whatever) and then putting the Arduino into sleep mode (and later resume it from RTC or so).
I like this approach, but after checking the wifishield doc I am not completely sure which are the power pins of the wifi shield that I should bend to put wifishield under control of Arduino. Do you have info or experience about this?.

About controlling the hole thing, to cut all the power supply of the circuit (and recover it later) from one 555timer(???), hardware, circuit, switch, thing... completely independatnt to arduino, and then one timer that connect the power supply again, that is valid for me too.
So any help of where to buy or build this or some tutorial or link in this way would be also appreciated.

Thank you, Your responses are valid for me to start researching

OK so here is a reference to the 555 timer one-shot that you could use http://www.555-timer-circuits.com/monostable-555.html

As for the pin to bend on the WIFI card it is the one marked 5V

OK so perhaps i might fit the bill but i live in France. I do already have a client that I am currently working with in Canada however.

Take a Quick look at my website WWW.EmbeddedAT.com and decide if you think I may be a good fit.

I work with start-up companies and help to take POC through to production. I have a couple of Kick starter projects under my belt as well. The most recent being "The Barman"

I fly a quad-copter based on, naturally, the ardupilot flight controller.

I have built stabilization systems for clients needing to maintain antenna position and am currently working on a client developing a 20 point self leveling platform.

Feel free to drop me an email to Peter@EmbeddedAT.com if you want to have a chat about the project with me or grill me about my skills smiley

Cheers Pete.

HI Rob,

Where in the world are you so we can tell if we are close or not smiley

That you think, I emphasize in CAPS , Is there any net rules at all? well No.

Well actually they are not fixed rules no,  just a well established etiquette of conduct for writing in blogs  and forums.

Something you perhaps might want to consider learning.

If you want to move this debate off topic i suggest that we find somewhere else to do it because, again , it is not good etiquette to hijack a thread for a personal rant.

Cheers Pete.

I give up .. no point continuing this if all you want to do is defend a confusing statement when someone asks for clarification.

this is emphasizing

THIS IS SHOUTING

learn your net etiquette

Cheers Pete.

Its nothing I made up I have the right to put my ideas in my way

Yes it is there is no such thing as "Deep Trodden" rooting. I Simply asked you to explain what that meant and you said "it just means rooting", therefor you made it up. I am not suggesting that coining expressions is a bad thing but your terms are a little confusing.

READ WHAT I POST CAREFULLY BEFORE MAKING REMARKS

Now shouting is just plain rude, but in keeping with the tone of your responses , so I am not surprised.

I suggest that you take a leaf out of your own book and read the post and its thread before posting. especial in light of the fact that you said that rooting is done to gain access to the USB port but the OP clearly states that he has this already.

You seem to be being very defensive about this, I am not sure why. All I asked for was clarity on your original post which was confusing and using self invented expressions.

Cheers Pete.

There is no such thing as deep trodden rooting, rooting is rooting or according to WIKI ( http://en.wikipedia.org/wiki/Rooting_%28Android_OS%29 ) gaining access to the kernel of the OS with administrator rights. There are no levels of rooting, Deep Trodden or otherwise mentioned.

Could you give me an example of Deep Trodden routing. I am learning this as i go along and any knowledge would be useful.

Deep trodden rooting means rooting only, its just the way to put it forward and may include bootloader unlocking because if you can understand rooting ,rooting means getting deep into the realms that are not controllable else you root the device, Hence rooting is always Deep Trodden.

That is interesting , every android device that I have use OTG USB interfacing with does not require "rooting" Admittedly I have only tried connecting FDTI chipset based USB-> serial bridge hardware but never had to root my device to gain access to it.

"That you have used" this is something not to explain here OTG devices are OTG devices that have Host controller chipset they are found in new versions ,there are tons of Android devices without any OTG support what about those and Even in the case of some OTG  supporting devices there is still need to root the phone and get the access to the specific functionality in the Kernel, a classic example to this are 2 year old phones from now, I have 2 of these which support USB OTG only after rooting and which also emulate Serial ports only after rooting and without Serial port emulation whom you are going to talk with, phones ass maybe.

How do the applications in the android store do this without root access.

Many of the Apps on the Android store don't work with unrooted phones and some work they work with high end devices which have OTG, you need to read the description of these apps in detail.
The fact that many USB host controller apps, stick mount apps require rooting, thats very common requirement called from such apps.



Ahhh OK so "Deep Trodden" is just something that you made up and does not actually exist, thanks for clearing that up.

I do believe that most new devices on the market these days do have OTG support .

perhaps you missed the post where the OP said .......

Yes i have an OTG cable and my phone support the USB Host mode.
I can connect pendrives,mouses,keyboards and controllers to it.


So I guess it does not need (Deep Trodden) rooting.

Cheers Pete.

Why would you need to root your android device in order to use the USB port with a USB-> serial adapter

Because every Android kernel won't give access to its drivers down under which are not to be utilised normally, I have done this several times with Android devices at my disposal, they dont have serial port emulated without rooting.

what is "Deep Trodden" rooting as opposed to plain old rooting ? I am confused .

Rooting is always Deep Trodden never plain old as such.

How do the applications in the android store do this without root access. Perhaps I have been lucky with my choice of hardware. I am not suggesting that it is never required. That would depend on the manufacturers choice on accessibility of the core systems. That said however I have not so far found any devices that would stop me gaining access to the USB.

Android always have drivers for dealing with the Serial protocol on the usb its just that they may not be accessible without deep trodden rooting sometimes of the phone!

contact me if you may want it done.

Why would you need to root your android device in order to use the USB port with a USB-> serial adapter  and what is "Deep Trodden" rooting as opposed to plain old rooting ? I am confused .

43  Using Arduino / Project Guidance / Re: Shorten code (help a noob!) on: June 28, 2014, 08:43:55 am
Code:
     digitalWrite(2,LOW);  //How do I shorten this?
      digitalWrite(3,LOW);
      digitalWrite(4,LOW);
      digitalWrite(5,LOW);
      digitalWrite(6,LOW);

becomes

Code:
for(uint8_t i = 2; i < 7; i++)  digitalWrite(i,LOW);

hope this helps

Cheers Pete.

send it as two 8 bit bytes and then re assemble it at the receiving end

using a uint 16 and add the first byte in then bit shifting the second byte and or-ing it with the first byte into the 16 bit unint

Cheers Pete.

If you can provide me a sample code because i could find one

look what a simple Google search reveals

http://forum.processing.org/one/topic/read-a-16-bit-data-from-serial.html

Hope this helps.

Cheers Pete.
