Single device multiple users

[szohar]

Hi,

I understand Blynk dont support multiple users on single HW.
I am trying to create my own by using a Segmented Switch so each user will be identified by different option [1-3]. I want to be able to get a command from the app and by poling the Segmented Switch to get the user ID. I couldn’t find any way to interrogate the Segmented Switch in order to get the user (interrupt will not help in this case since it does not changes often).

Your help will be greatly appreciated.

Thanks
Sharon

Here is a good example of

case

Garage Controller

Here is a copy of my code. I’m waiting for the new iOS version to try some of the new features. /* V0 - ADJUSTER * V1 - TEMPERATURE * V2 - SETPOINT * V3 - DEADBAND * V4 - VALUE++ * V5 - VALUE-- * V6 - ADJUST++ * V7 - lOW SET * V8 - OUTSIDE TEMP * V9 - LOW HOUR * V10 - HIGH SET * V11 - HEATER STATE FOR TREND * V12 - ELAPSED TIMER * V13 - HIGH HOUR * V14 - DIAGNOSTIC CODE * V15 - DOOR OPERATOR * V16 - OPERATION * V17 - DOOR SWITCH * * EEPROM0 - SETPOINT * EEPROM1 - DEADBAND …

can you make use of this somehow?
(when a button is pressed, use the value of the seg-switch to do something)

BLYNK_WRITE(V5){
  if(param.asInt()==1){
    switch(adj){
      case 0: set--;count=1;updateData();break;
      case 1: db--;count=2;updateData();break;
      case 2: low_set--;count=8;updateData();break;
      case 3: if(low_hr==0){low_hr=23;}else{low_hr--;}count=9;updateData();break;
      case 4: high_set--;count=10;updateData();break;
      case 5: if(high_hr==0){high_hr=23;}else{high_hr--;}count=11;updateData();break;
      case 6: if(oper==0){oper=2;}else{oper--;}count=7;updateData();break;
    }}}

Thanks,
I am guessing the V5 is the seg-switch, if you have multiple users sending info to a single device, how do you know from here who sent the info, the count in your example will change on the HW but the info can come from any device. I need to be able to send a location from multiple phones and to behave based on the phone that the info arrived from.
Thanks

maybe this might help?

Comparing two Virtual Pin Values

i have same problem. how to compare two virtual pin value? edit: i solved my problem: sample code written on http://docs.blynk.cc/#blynk-main-operations-virtual-pins BLYNK_WRITE(V1) //Button Widget is writing to pin V1 { int pinData = param.asInt(); } simple, int command used in BLYNK_WRITE(V1) scope. this example, everywhere like this. my solution is this: int v3=0; int v4=0; int v5=0; BLYNK_WRITE(V3){v3 = param.asInt();} BLYNK_WRITE(V4){v4 = param.asInt();} BLYNK_WRITE(V5){Tim…

i guess i made some assumptions… like you would have a segment switch… to declare the user-id … and then a button to activate the (lets say led for this example) led.

so…if i was going to turn on the led, i would hit the seg-swtich with my name, then hit the led button…

Hoping im following your attempts correctly.

the caveat is that if i didnt want you to know it was me that turned it on… i could make it appear as if another user-id hit the button.

I am not sure this will help, each mobile phone is updating its own location (unsynced), how can I know who sent which location if they are all running?
