• issue with 1v92 on puck - pulsing leds

  I haven't worked with my pucks in awhile but this weekend I tried installing the v92 and had the same problem with the 3 flashing leds. But your fix to wipe the flash worked fine and v92 installed correctly. Thanks!

  when I turn two adjacent LEDs on, one of them is extremely dim

  You might share your circuit schematic. How are your LEDs biased?

  Glad I could help. I have a few decades of experience in discrete logic. When I saw 74HC... I was intrigued. Sounds like you are a lot closer to your goal. Good luck!!

  You might consider posting your entire program. But I'm thinking, s.write sends characters, not bits. Is that your intent? You might be shifting a lot of binary zeros before the transfer to the output.

• Puck js, how to send MQTT message with button pressed?

  No experience with Olimex A20 unfortunately. I did easily get the hub to work on an Odroid, however, so I know it can work on other platforms. Though once I tried it on the RPi 3 I just left it there.

  I use the Plugable USB dongle on my Windows 7 Pro machine to talk to the Puck with good results. On my RPi2 hub I used this one from ameriDroid (via Amazon) with good results prior to my switching to the RPi3. The RPi3 works well also.

  I got that one since I really wanted to use my Odroid XU4 as my Espruino Hub. And that is the official BT/BLE dongle for it.

  @Gordon

  I found this in one of my old posts. This is the specific syntax I had to use to get my /ble/write to work properly from the linux command line. It has to do with how the linefeed character gets passed through if I recall. But I don't know if this relates at all to the problem @Grzegorz is having.

  mosquitto_pub -t /ble/write/c7:6e:71:dd:ee:ff/nus/nus_tx -m $'digitalPulse(LED3, 1, 200);\n'

  @Gordon I don't think I have seen that particular error before. But from the output it's odd that the service appears to have been translated to its UUID format but the characteristic has not. Maybe there is a subtle problem with the mqtt publish and/or interpretation by the hub.
