LEDs for 52840 dongle not working

[mame82]

The LED assignment for 52840 dongle isn't working at all.

Here's an excerpt of my board definitions, with respective comments on LEDs.

RED isn't working at all. Blue and green show weird behavior.

LOGITacker firmware for the dongle was added:

There is an interresting observation here. adafruit/circuitpython#1174 (comment)

[mame82]

Behavior differs ... especially on BLUE LED ... not sure on undervoltage

#define BSP_LED_0      LED_1 // blue, bright
#define BSP_LED_1      LED_2 // blue, barely noticeable
#define BSP_LED_2      LED_3 // green, only if LED_2 is on, too
#define BSP_LED_3      LED_4 // seems to toggle LED_2 somehow, without changing LED_4

@mame82 When did you buy the USB dongle? We'll try to re-produce the issue with your code first

[volca]

I just tested one dongle with a test firmware. Please check the video.

Here's the firmware file
nrf52840.uf2.zip

Some early dongles are soldered with wrong RGB led so it has the issue.

Thanks @volca , but your video only show green blinking LED, and the blue LED. @mame82 mentioned that the issue is getting Red LED, and Green LED is only working together with Blue.

The video shows blinking green --> blue -> red. Please check it again?

No, all 4 LEDs are shown (single color blue and RGB).

Unfortunately it still doesn't work out with my dongle, here's a video from the LED test firmware provided above video.

The dongles was have been ordered on May 16th (order #2169). Only 1 out of 3 arrived, still waiting for the others ... maybe it is a malfunction of the one which arrived.

Also, is there a way to disassemble the dongle, without destroying it. I noticed that you removed the upper side from the housing. On my version, the upper part of the housing is holding the USB-A plug together. Removing it would render the plug unusable.

I can confirm the dongle was soldered wrong RGB LED. We've replaced all RGB LED for other dongles. Two dongles with new RGB LEDs were shipped out yesterday.

Unfortunately you must destroy the casing to disassemble the dongle (I also destroyed one casing today). But we can send some more new casings to you if you place another order for the dongle.

OK, my bad, sorry guys. I also ordered new dongles (the ones I had are bricked), will be looking forward to test once they arrive. @volca it seems my order 2310 is just about to ship, perhaps you can manage to add some housing to that ?

So this means this issue does not exist, anymore! Nice.

Btw. the external antenna performs really well, compared to the Nordic version with PCB antenna.

Looking forward to test the new dongles ... thanks for the support!

@nieldk My colleague are making package for order #2310. She will add extra 3 empty housings and one more usb dongle to the package.

Marvelous, thanks guys!
I will forward some to you @mame82 if you would like ?

[volca]

Thanks @mame82 and @nieldk for get the dongle compatible with the great software LOGITacker!
