Is it possible to flash a NRF24LE1 IC using the NRF51-DK as programmer?

[mafaldo]

Hello everybody,

I have a NRF51-DK board and I want to acquire some NRF24LE1 chips. I haven't used the NRF51-DK a lot but I have seen somewhere that it is possible to flash NRF51 IC's with it (correct me if I'm wrong). I was wondering if it is possible to use this board to flash NRF24LE1 IC's as well. If so, could you please tell me how? I'm new to all this stuff, I haven't used any nordic products before.

thanks!

Hi,

The programming interface for nRF24LE1 is SPI, so it's possible to say any board that support SPI can program the nRF24LE1.

However, there is no tool or example made to do that on a nRF51DK.

In other words, it's possible but not out-of-the-box. It's not the same as programming other nRF51 IC, as you can simply use the Segger chip on the DK to program the external nRF5 IC.

You would need to develop your own programmer using the nRF51 chip on the DK.

So the question becomes: Is the SPI programming protocol for the nRF24LE1 published somewhere?

And, if so - where?

@awneil: Of course it's published. Check out section 6.3.5 in the nRF24LE1 Produc Spec v1.6

Thanks for the quick reply! I'm sorry I couldn't thank you before, I was traveling. However, I already downloaded the documentation you mentioned, I will try to follow the steps described there to program the chip using SPI.
