nRF52832 production programming

[Lyka56]

Hello!

nRF52832 IC supports programming OTA the first time after its soldered onto a custom design?

We are designing a very small form factor wearable product and would like to avoid having programming connectors on the product board.

TIA

No it doesn't, you have to program it once first.

You may be able to get your manufacturing house to program the chips for you, there are QFN48 sockets in existence which can be used to program the chips before soldering, although where you get them I don't know. Someone asked here about it a while ago, and I thought there was a blog about a programmer someone else made.

.. and devzone.nordicsemi.com/.../ is the blog about it.

Hi, I think that the fast solution is to program the device on-board (via in-circuit programming -- SWD protocol). You don't need a programming connector but it's enough to place the TP pads (test points) for programmig. Then you have to build a programming fixture in order to program the panel of boards.

If you need a professional in-circuit programming solution, take a look at www.algocraft.com The WriteNow! programmer is able to program up to 8 devices in parallel, but it is also able to handle up to 32 devices using one unit. The programmer supports variable data programming (like MAC address, serial number, production data, etc).
