Some pictures of an assembled unit with 3d printed case

waspie

I'll be updating this with pictures of actual boards soon, including my PIR "hat"

I've been running several of them for about two months now on a single CR2450 (~620mah) and they're still showing just slightly over 3 volts. These are detecting motion many times per hour during the day.

this is great info, this could potentially help a lot of people on this forum

I have quite an annoying problem keeping me from successfully deploying a bunch of NRF52 PIRs.
For a little while it works and then the messages stop. I have serial logs from the NRF52 seemingly sending the messages but nothing on the gateway side. The two devices are about 6 feet apart. I've tried it at home with a completely different pi and a completely different radio (pa and non-pa version) and the results are the same. On my desk at work its a regular pi b with a non-pa radio. Again, six feet apart. I've tried the default channel. I've tried channel 10 and 125 as well. I've tried max power and low power. I send the message twice thinking maybe one gets lost and the second makes it through.

Here's the sketch:

// SUMMARY: This demo sketch runs on the AM612 PIR v607 PCBto transmit battery voltage (heartbeat) and motion detections to a MySensors gateway using MySensors protocols.

// Note: because this is a passive node, node ID must be set manually to a unique sensor node ID:
#define MY_NODE_ID 70  // Passive mode requires static node ID

//#define MY_CORE_ONLY

//#define MY_PASSIVE_NODE

#define MY_RADIO_NRF5_ESB



/**
 * The MySensors Arduino library handles the wireless radio link and protocol
 * between your home built sensors/actuators and HA controller of choice.
 * The sensors forms a self healing radio network with optional repeaters. Each
 * repeater and gateway builds a routing tables in EEPROM which keeps track of the
 * network topology allowing messages to be routed to nodes.

any hints would be more than welcome, please

waspie

is there an option to run a pi as a repeater? I didn't see anything in configure help

waspie

its the start of a nrf52832-based motion sensor similar to neverdie's Multi-Sensor: Temp/Humidity/PIR/ Leak/Magnet/Light/Accel seen here:
https://www.openhardware.io/view/510/Multi-Sensor-TempHumidityPIR-LeakMagnetLightAccel

The nrf51822 is a bit finicky. I made it slightly bigger to accommodate a cr2450 and use a nrf52832 which is allegedly more reliable for low power sensors. I have a PIR hat, too, that i need to upload. I made my version adjustable. Neverdie's version works, but, the pir triggers quite a lot at the minimum reset time which means its triggering often in a busy room which uses a lot more battery.

waspie

my pi3b does this as well. it's far and few in between. I even made a watchdog in openhab to "ping" the msgw (requesting an ack) and mysgw responds but it doesn't send out new sensor readings. i thought about expanding the watchdog to watch for all sensor readings and throw up a restart to the gw if it receives no readings in a 10 minute period but mine doesn't fail nearly as consistently as yours so I haven't worried about it too much...

would still like to see a resolution to this as I've moved most of my PIRs and temp sensors to mysgw so when it goes down it can be a bit of a problem.

waspie

oh yeah, forgot to mention unplugging it after programming. that has bit me in the butt at least 20 times. finally i remember to unplug it now /facepalm.

waspie

i've only played with the nrf51 but i know well enough getting either of these to fully sleep can be a bit of a process software-wise. i doubt you need any hardware, it's going to be software related

waspie

For anyone looking to use @NeverDie 's nrf51 circular board (v9) with this breakout - I'm using the sketch as linked from @Nca78 in this post: https://forum.mysensors.org/topic/6961/nrf5-action/1542
in conjunction with the edit to the file as described in this post:
https://forum.mysensors.org/topic/6961/nrf5-action/1514 (the edit to WInterrupt.c and I'm using version 0.6.0 from sandeep)

with just a few minor edits to the sketch from Nca (setting the pin to 10 (sda marked on the circular board).

14ua idle current btw, working like a charm. so far i'm just using a 2032. Trying to figure out a way to strap a cr2450 or 2477 on the back
