That's a good point, I missed that detail in the ds. The sensor is now in service, I'll measure it again when i have a chance. Thanks.

VEML6075 high sleep consumption
I've been reading the thread here, and decided to open a new one since that one is old, and there were no reports of the consumption being fixed.
I'm in the same situation regarding consumption of my VEML6075 board being around 50 uA while sleeping, when it should be less than 1 uA according to the datasheet.
My specific board doesn't contain any voltage regulators, just a capacitor and the I2C pullups. Specifically, it's this one:
I'm using the adafruit library but I've tried 3 others with different sleep routines, all with the same result. When active, the consumption is much higher, so the chip is sleeping (sort of) it seems.
Any help on reducing the sleep consumption would be appreciated.
RE: Sensebender Gateway RFM69HW Decoupling Capacitor
I also had to limit power to 13 dBm; in my case I think the reason is that the board needs more power than what the battery can provide when over that level, but I was never able to prove it.

Hi, I'm interested on using the functions in the post title. I'm running Mysensors 2.2.0., and I have
in my sketch.
If I add something like
to my sketch, the Arduino compiler complains about undefined references.
What do I need to do to get them working?
RE: RFM69HW connection to 2560 Mega Pro board
Answering to myself... after many tests I decided to start to start working backwards and started to discard assumptions... finally I discarded :
I know that Mega pins are 5v and in theory RFM69 are 3.3v, but I have more sensors installed in a similar setup with mini Pro 5v and Nano boards that work perfectly.
So I fit a ttl levels shifter between the Mega Pro and the RFM69 and it started to work right away.
It looks like AT328 and AT2560 have different levels of sensitivity as of being able to interpret 3.3v correctly as a "1". Interestingly, I checked the datasheets for both chips and the specification is the same, min 0.6Vcc volts, so anything over 3v should be interpreted as a "1"... go see...
As a final detail, I was able to use a 4way ttl shifter since the MISO line doesn't need to be shifted, which left me with MOSI, SCK, SS and INT. Credit to this forum page for this:
I can also confirm that pin D2 on these boards is connected to INT0 as standard... I don't know why the pinout diagram indicates something different.
I hope this helps others.
RFM69HW connection to 2560 Mega Pro board
I'm building a sensor using a Robotdyn Mega Pro board.
The pinout of this board is here:
My network uses RFM69 antennas.
My connections are:
Power is connected to 3.3v line. I know that Mega pins are 5v and in theory RFM69 are 3.3v, but I have more sensors installed in a similar setup with mini Pro 5v and Nano boards that work perfectly.
I have also tried two different radios to discard hardware issues.
On start my sketch shows:
3 TSM:INIT 4 TSF:WUR:MS=3000 106 !TSM:INIT:TSP FAIL 108 TSM:FAIL:CNT=1 109 TSM:FAIL:DIS
My concern is that pinout diagrams for "normal" Mega boards show that pin D2 is assigned to INT0, while the pinout for this board linked above indicates that pin D2 is assigned to INT4.
In view of this, I have tried adding the following defines with no success:
#define MY_RFM69_IRQ_PIN 2 #define MY_RFM69_IRQ_NUM 0
I have tried all numbers from 0 to 5 for MY_RFM69_IRQ_NUM.
I also tried pins 18 and 19. I can't use 20 and 21 since I'm using I2C comms.
No matter what I try, I'm still getting the same error.
I searched through the forum and on the inet with no success.
I'd really appreciate if someone could point me in the right direction... thanks!
RE: 💬 Soil Moisture Sensor
The info in the page is confusing. The small board between the sensor and the arduino is an on-off level switcher. It provides a digital binary singnal so can't be connected to an analog pin on the arduino.
If you wish to measure the moisture level with an analogic scale, you need to eliminate that board and then use a voltage divider and an analog pin. The sketch will be also different. Everything in explained above in the thread.
You may want to read the full thread and then don't hesitate to come back with your questions.
RE: Sparkfun8266 Wifi Shield + Arduino Due = WiFi Gateway
@zachflem There are no ESP based boards wich such a high number of GPIOs that I know of. But there are some MEGA + ESP boards out there. I'm not sure they would work with Mysensors but may want to have a look.
