Need help with deep sleep NRF51822 board #22

Open MegaSegaDrive8 opened 1 year ago

MegaSegaDrive8 commented 1 year ago

Hello. Thank you for this library.

I need help with deep sleep with board nrf51822. Now for example "delay(5000);" get me about 0.8-0.9 mA.

Is this maximum mA for sleep mode?

h2zero commented 1 year ago

You're welcome 😄 , is there anything else on the board drawing current? On my nrf51822 boards the current draw is much less in sleep mode. What peripherals are you using?

MegaSegaDrive8 commented 1 year ago

No, just 2 contacts like switch, between GND and P16

Maybe I have a problem with the code. Do you have any example, for example, just advertising for 1 second when the contact is closed between P16 and GND?

I don't have any examples of that at the moment but I am wondering if you are calling Serial.begin() in your code? the UART will consume power at that level.

hello guys; @MegaSegaDrive8, i was wondering if you can share your example code, I wanted to do exactly the same thing, i want to advertise a custom payload and then send it to sleep, would be able to share at least the nuts and bolts. @h2zero i did also check your other repos but i was not able to find the deep sleep for nrf51822, great work!

@beckmx systemPowerOff() will put the device into deep sleep while just calling delay() will put the device into "system on" sleep mode.
