RAK19007 how to turn off with reset button

WisBlock
1

Howdy,
I’m wondering if someone could tell me how to do two things

  1. set the RAK19007 baseboard rest button to allow the 5 second hold to turn off the unit
  2. can I solder an remote reset button by piggybacking off of the original header connections that the reset button is attached to now?

Welcome back to RAK forum @IronSpear ,

For #1,

The reset button is connected to the actual RST pin of the microcontroller of the WisBlock Core. Some MCU in the market allows reconfiguration of RST button (even useable as GPIO pin) but this is not something natively supported by WisBlock. Also, with “turn off”, does it mean sleep mode or electrically off (power disconnect)? A power off button (holding it for 5 seconds) implementation should be possible but unlikely to be done on the reset pin itself.

For #2,

You can piggyback on the reset button but we do not have RST pin header on standard and mini baseboards. RST header is available on Dual IO baseboards (the bigger ones).

Hey Carl,
Thanks for the reply! Good information.
I see the RST header as I’m running the larger base board.

If I run a button to the RST header do I run the opposite side the pwr or gnd?

On the topic of turning off the power to the board, somewhere within the documentation I could have sworn that there was a feature that said by holding the RST button you could power off the base board.

If I can’t do that then I suppose I need to have 2 buttons. One for RST so I can do firmware updates and one between the battery and the board.

Hi @IronSpear ,

The other side should be GND to perform reset.

With regards to holding RST, I can’t remember we support that. On our field tester, we have a button that when you hold, will initiate turn off but not on WisBlock Core level.

1 button for reset and 1 switch for turning off.

Thanks again for the reply Carl.

Not sure if it makes any difference, but this is on a 19007 with a 4630 Lora unit running meshtastic.

I think I can run a DPST micro switch and solder the rest wiring on one side and the battery on the other, and if I toggle twice quickly I should be able to put it into firmware load mode or hard off the battery. does that sound like it would work? Ill see about testing my theory.

Oh. I haven’t tried this approach but the when you double click reset to enable bootmode, the device should have stable supply. Well, this is something you can try yourself. If not possible, you really need to have access on the reset button.
