Sending string over eddystone tlm

[asmita_patil]

i want to send string over eddystone tlm...and wish to use temperature part for this...so how can i display character string instead of temperature in eddystone TLM..please help

Why do you want to send it as a string?

The Eddystone TLM specifications are here:

TLM is just a transfer protocol/format - it  has nothing to do with display.

Are you confusing displaying the data  - which is what an app does - with transmitting the data - which is where TLM comes in ... ?

i am done with what i was willing to do...i can now see the status of a button whether it is pressed in place of temperature....

the only thing is that when button is not pressed it shows 0.0 c and when pressed it shows 1.0c...why does that degree c of temperature is showing....is it controlled at application side....i am using nRF Beacon for eddystone ....plz reply..

Yes, it is controlled on the application side. See the button event handler function. Also, make sure to take a look at the documentation here. The es_app_config.h header file could be useful to look at too.

but it takes a lot time to display button status...even if i press a button it takes  a lot time to make led on (as an indication )(i wrote it that way) and then displays 1.0 c  on screen then again takes lot of time to led to go off and then it shows 0.0 c on screen.....why is this so....????

i need to refresh (in nRF Beacon for eddystone  app) again and again to see the change..

can you explain everything plz..

Thank you so much.

i have one more question

on button press eddystone starts connectable adv...as the below function says..

but again take a look at function below

nrf_ble_es_init(on_es_evt); is called in main()

then whatdoes this "es_adv_start_non_connctable_adv();" function means.....????

does this starts a non connectable adv..???

if yes the why we stay connected in app???

Hi, 

Please tell why you want to use Eddystone to show text when it supposed to show temperature  ? 

I would suggest you to have a look at the ble_app_blinky example, the counter part for that is the nRFBlinky app  on the phone. 

[asmita_patil]

that is what requirement is.....but i managed to check button status instead of string...thank you for your response...and i will go through the example..

thank you so much.
