recommendation on hardware configuration of nRF52

dear all,

I'm a newbie on blue tooth low energy development, I have some really basic questions that I hope someone could answer, thank you very much in advance!

what I want is to add wireless connectivity to my system. I have heard Nordic produce high quality BLE device. here I am.

Description of my current system: the system is a wearable device that measure heart rate, temperature signals. The system are based on PIC microcontroller and other sensors. The system is already developed but currently the data are sent out via cable, I'd like to connect a BLE device to my PIC MCU and send data wirelessly to my host.

Following are my questions:

1. I heard nRF52 are very good devices for BLE, please advise me any particular device for my need. My top priority is easy-to-start, since I have ZERO experience with BLE development. The next requirments are power consumption, and size of the devices.

2. What is the hardware configuration of nRF chip in my system? How do I communicate between my PIC and nRF to configure nRF, and transmit the data between the two device?

  • Hi Simon,

    thank you for your reply.

    I see that 840 is a more powerful device than 832 from your description and your website, I also realized that according to the spec, 840 is less power consuming compared to 832, which is favorable. 

    I'm wondering besides being more expensive, is there any other reason to not use 840 to 832? For example, it is more difficult to program 840 than 832?

    Another question, could you please share an example / link of using I2C to transmit data in a transparent mode?
