External Sensor data broadcasting

[amj]

Hello everyone, I would like to make the following application.

I want to connect a temperature sensor to nRF51822-beacon to broadcast the temperature measurements

First, how would you approach such an app?

Second, my questions:

a) I know I need to convert the analog signals to digital, and there is an expample about that (simple_adc_pca10028). However, what I could not find is which variable capturing this data/ how to extract the converted data?

b) How to append this data to an advertising packet (which needs to be changed every advertisement)?

Thanks in advance.

Hi amj,

a) After running an ADC conversion, the result is stored in the RESULT register. You can also call the function nrf_adc_result_get defined in nrf_adc.h in the HAL of the SDK.

b) This answer is similar to what you are asking. Essentially you simply change the advertising data each advertising packet (or at whatever rate you need to update the data).

Hope this helps,

Eric
