Acquisition information from external sensor

[Angelo Cotroneo]

Hi all,

I have the nRF51822 chip and I want to acquire external sensor (i.e. pressure, temperature) and send the information via bluetooth.

I need to configure the I/O pin to acquire the information. Can you help me?

What is the basic code to configure I/O as analog input and to send the information via bluetooth?

Thanks a lot and best regards

Hi,

You need to provide much more information?

• What sensor?
• What serial interface are you going to use?
• Which SDK are you using?

We can't write the code for you but we can help you find a proper example that should be a good starting point for you project. For example, the ble app uart example is a good starting point for sending data over BLE.

Hi Jared,

regarding your question, the answer are the following:

• What Sensor? Analog sensor (pressure, NTC, PTC, etc.)
• What serial interface are you going to use? I think to use the UART interface
• Which SDK are you using? I think to use the SnRF5 SDK 16. Is ok for my scope?

Thanks a lot and best regards

Hi,

The nRF51 is supported up onto SDK v12.3.0. Again, the ble app uart example would be a good starting point, I suggest that you start with that example.

Hi Jared,

thanks a lot for the clarification. So I would use SDK v12.3.0.

What kind of hardware do you suggest me to use to start with the application?

Thanks and best regards

 As in which sensors you could use for retrieving the temperature and pressure? Well, we use LPS22HB on our Thingy:52 which is our nRF52832 based prototype platform that has several sensors for measuring pressure, humidity, temperature, sound etc. You can read more about it here.

Hi Jared, thaks a lot for the answer. An other question. I have bought this evaluation kit to program the nRF51822.

Can I use the same SDK to program my chip? Can the tool work correctly with this hardware?

Thanks a lot and best regards

Hi,

I'm not sure as it's a third party product but my guess is Yes. In general, SDK 12 supports nRF51 and thus should be able to flash that kit.

Hi Jared,

thanks a lot for your help :-)

I am waiting the shipment of that HW and I will start my adventure ;-)

I will update you if you want

have a nice day and best regards
