Starting with nRF52832

[KYUBEEN]

Hi, I'm just a beginner with Bluetooth. I want to make a simple bluetooth module, so I just bought nRF52832 and other devices like capacitors, inductors, crystal oscillator and antenna.

The thing is, I have no idea how to start with these chips. I was planning to make pcb with these, but wander is there any process I should do with nRF52832, like start setup.

I'm gonna make pcb with the reference layouts and have all components plus chip antenna.

In sum, I want to know overall procedure to make a new bluetooth module with nRF52832 and other components in the reference layouts. Please give me a big help. thank you.

Hi

All you need in addition to what the reference design provides, is a way to power, and to program the nRF52832. I suggest you mount the following GPIO pins:

• One pin connected to VDD, for voltage input
• One pin connected to ground on the board.
• One pin connected to SWDIO and one to SWDCLK. (Necessary to program the nRF52)
• Optional: One pin connected to an analog input (AIN) for testing purposes.

Keep in mind that this is the most basic way to make a bluetooth module, and you may want to add more input possibilities for additional features.

Best of luck,

Simon

Thank you for your kind reply Simon.

I understand the needs for the pins, connected to VDD and ground, but still not sure about SWDIO and SWDCLK pins. I thought basic program is set in the nRF52832. So, if I connect the pins for VDD, ground, and AIN, is it possible to get simple signal through bluetooth?

For example, assume I made a module( just by mounting the nRF52832 and other components) with reference layouts, plus antenna. Also I connect 3 GPIO pins for VDD, ground and AIN. In this stage, if I set analog input as 2 DC voltage, is it gonna send any signal through bluetooth? Just simple signal. I don't need any complicate control since I am starting as a beginner. I just want to check out any bluetooth signal.

Thank you,
