Read and write data with single UUID

[aliyolcu28]

Hello,
How do I program the NRF52840 module to read and write data with a single UUID, because the mobile application I used earlier was working with the data read and write over a single UUID. The Android code section is available in the appendix

.

I can read and write data with the HM_RX_TX part in the picture. How can I do this with nRF52840 with the current application?

I've been using this module for one day. I don't have enough programming knowledge about the module, but I'll try to review the links you've posted, thanks.

If you have a ready .hex file, I'd like to quickly see and see if it works in the mobile application.

When starting with any new device or technology, it's always important to spend time getting familiar with the technology in general, the particular device, it's tools, etc.

The best way to do that with the nRF52 devices is to get a Dev Kit, and play with the tutorials & examples:

Are you familiar with programming any other microcontroller(s) ?

Are you familiar with programming in general ?

I already have a development card and j-link programming kit in my hand.

 I've been doing embedded system work for about 2 years, and I'm usually working on processors (TM4C123 *, TMS570 *).

It's always easier to start with the manufacturer's own Dev Kit - because then you get the ready-to-go examples and support.

But, at the end of the day, the chip neither knows nor cares what board it's on.

You'll just have to make some minor tweaks to accommodate the different board.
