@omemanti Yes I will. This is a long thread to catch up ;-), but I did find that the latest revision of the breakout added room for the inductors to use the DCDC mode.

I guess it takes some more reading & doing to get the firmware loaded on those Ebyte modules, but as others did that already I'm confident that that will be ok!

It will be my first nRF52 application.

@alowhum, you seem to need Jlink Commander:

@toyman said in nRF5 Bluetooth action!:

@alowhum I intentionally asked you because I know the problem exists.
You need to erase the chip via Jlink Commander. Neither nrfjprog nor anything alse will work (AFAIK)
Actually, it was @NeverDie who found it in the beginning of his quest with nrf52. "The thing that started it all" (c)

Furthermore, It would be nice to have a small step-by-step guide to unlock and then program the ebyte module.
@Omemanti and @NeverDie are using these modules, so should be able to write something up that works for other ppl ;-)

(My ebyte modules are still on their way)

A bit off-topic, but as per the suggestions earlier in this topic I managed to get a toaster oven working with an OSPId reflow controller, and got some test boards with 0603, 0805, 1206 and SOT23 stuff reflowed with 4 year old AIM solder paste (no flux, lead free of course).

Learned a lot. Now should get my hands dirty with some nRF52832 (ebyte E73) modules / PCB's to produce something useful ;-)

I see so much nice designs here with that module!

@neverdie No idea if this was difficult as I never worked with leaded solder paste :laughing:

I used OSPID's RoHS reflow profile to reflow a test board

The test board looks like this. I was surprised that I managed to place the 0603 (imperial) with a pincet on the board (and magnifying glasses).

No idea how good the connections really are with 4 year old solderpaste. I guess I should not use that for real boards :sunglasses:
