ARDUINO plugin discussion

The iPhone kinda works but not reliable. It switches off its ble signal.

Will walk you through when you get it.

It's not a big deal...the Android one is more important since he doesn't have access to the system. I'm currently using Home Remote on the iPhone to trigger when I get home via geofencing, so I'm ok.

Dunno if the iPhone 7 Plus might allow smoother BLE stuff...should have it in 2-3 weeks (pre-orders opened at 2am central and by 2:30a shipping days had started slipping a 1-2 weeks.)

iOS 10 might have more BLE capabilities since its designed for the new wireless headphones and all.

Its a principle thing. The phones want to save battery and hence they switch off communication signals after some minutes. Their signal strength are high ~ 0 dBm.
Ibeacons send a very short package every 0.x seconds at ~ -60dBm. Their battery lasts 6- 12 months. They are ideal for presence detection.

Went to convert the sketch to FREE device and found a typo in the sketch.

Code: Select all

//
#if defined(FREEdevcie)
     #define maxAnalogValue 10000
     #define serialBaudRate 57600
#endif 

FREEdevcie typo instead of FREEdevice

I corrected my base sketch.

Now, when I tried to compile and upload the dual DHT sketch, I ran out of memory.

Code: Select all

This report would have more information with

option enabled in File -> Preferences.


Commented out and turned off DEBUG and now I get it down to:

Code: Select all

Sketch uses 22,784 bytes (70%) of program storage space. Maximum is 32,256 bytes.
Global variables use 2,106 bytes (102%) of dynamic memory, leaving -58 bytes for local variables. Maximum is 2,048 bytes.

Any ideas for reducing the last bit of memory to fit?

I'm definitely down for moving to the RPi, but don't want to lose the $ invested in the Arduino hardware either.

Nevermind...I forgot I had another MEGA board in my stash so I just changed the hardware to that and no more memory issues. I'll use the more limited UNO units for simple stuff like single DHT or ONEWIRE units, plus the digital pins for some magnetic sensors I have.

make sure you select UNO for an UNO. the default UNO setup leave some 500 bytes for variables

if you run into problems you can empty the special function ( delete all like besides {} ). that should give you some bytes ... but the UNO is indeed limited in RAM. It is MANY years old..

Finally I've set up an UNO and a DS18B20 to read the temp.

In the device setting I have PIN 2 set as INPUT
The device is created, but I have no clue where to set something in the plugin?
Which menu option from the plugin do I have to use? "Plugin Set Pin"?
How can I read the temperature?
Do I have to set a variable first? Where in the plugin?

Karl, please help!

In the sketch you read d2, write the temp to eg s0. In the plugin you read s0
No d2 in the plugin

Karl, ok.

But in which of the options in the plugin do I have to enter it?
Can you send me please a screenshot?
I can't check it out!

in device edit you define the mode of the pin (enable/disable S0 variable = input)

the output is for sending data to the arduino

in device edit you define the mode of the pin (enable/disable S0 variable = input)

the output is for sending data to the arduino

I don't have in device edit ("enable/ disable S0 variable") input.
Only off, read fro string and output???

I think we have to do it via Teamviewer when you have the time.
I'm completely confused now.

read from string

read from string

Ok, last try for today, then I will give it up.

That's what i have now set in the device and plugin.

Temp doesn't appear

ONLY one setting:
SO read. NOTHING ELSE !!!!

D2 off ..

then make sure S0 gets filled in the sketch in doMystuff()
