@berkseo said in NRF51-52 PA not support ???:

The network is simple, this node is nrf52 with an amplifier and a gateway with the nrf24 radio module with an amplifier. It would be strange if a gateway with an amplifier could not deliver ACK. Two moments, or I did a very bad control of the amplifier on the node nRF52 or in the radio driver itself, something is not working well, and may need some delay settings. If i send messages with an ECHO (soft ack) request, this works fine over very long distances. Hw ack does not work properly.

Someone was able to do this for mysensors? Gateways and repeaters on nrf5 with amplifier is a very, very cool topic.

added support for E-Ink DES to the project. Further test in the refrigerator

@mfalkvidd said in Air quality and weather forecast sensor:

Do you have any special plans for what to do with the award? (It is of course ok if you prefer to not share your plans)

I will further develop this project, I also have many other projects and ideas.

I just got an email. It was unexpected :). This project of an air quality sensor that works on Mysensors became one of the finalists Hackaday Prize Challenge 01: Rethink Displays.

updating the project to v 0.54

I think this open source project is finished. This is a small air quality sensor. Quite a useful thing turned out for our not simple time.

https://github.com/smartboxchannel/EFEKTA-EINK213-AIR-QUALITY-SENSOR-NRF52840-V2-ED3

I looked again at this old project. It runs on the modified Sandeep mystry library which is on my Github. Just try to choose the board nRF52832, everything should work perfectly on it. And a little later I will update this repo for the 0.7 library

@killah78 said in nRF52840 MINI DEV BOARD EFEKTA:

undefined reference to

It's not clear why it doesn't download these files. I re-uploaded the ino file to github. Try downloading it and compiling it again.

@killah78 Hi,
I haven't been using the MyBoardsNRF5 layer lately.

To compile everything, you need to add that transfer rate. In version 7 of the library from Sandeep mystry, updated files from the Nordic SDK were taken. There is no longer this speed, but you can add it yourself.

@killah78 Hi, you can use the instructions for example from this project of mine( readme file) - https://github.com/smartboxchannel/EFEKTA-EINK290-TEMP-HUM-PRES-WEATHER-MINI-STATION-NRF52#instruction

@nagelc
Wow, this is unexpected.

@NeverDie said in Coronavirus (way, way, off topic):

If you hop across over to Russia, you might be able to get inoculated with Sputnik V. Although it was initially greeted in the West with skepticism, it has since gotten thumbs up from a proper peer review in Lancet.

Here, vaccination is not very popular, many are in no hurry to get vaccinated. I do not know what this is due to, I think mainly because most people are sure that they have already been ill and received immunity)). Judging by the statistics published here periodically, Sputnik V works well and has almost no complications.
... I'm not sure if it was skepticism, rather something else.

@berkseo

@NeverDie sgp40 sensor is used, I also test the bme680, but the results are worse there.

Hello everyone. I want to show you my new device, battery powered air quality sensor. The device also has light, temperature, humidity, and atmospheric pressure sensors. I am currently testing the software.

@ncollins
Very, very beautiful project! I also already have several such radio modules from different manufacturers. Here are just these ebyte specifically, they are without dc-dc. ...I plan to transfer support from nordic sdk to sandeep mistry (just like I did with 52810 and 52811), but how do you flash them under mysensors? Maybe there is already some shorter way?

Hello,
sorry for my poor english.. I don't speak it very well...
I just want to know if you plan to sell assembled card in the future? I'm very intersted by your project but don't have the possibility to sold the component.
Thanks for your answer.... and I cheer all of your project.

Yes, I am planning to sell this device in assembled form. Even now, there are many orders that I am very slow to complete. The problem with both COVID-19 and the fact that I am not very happy with the Chinese sensors that are used in my project. I will replace them with my own and soon complete all orders.

The other day I received PCB of a long-awaited project. Yesterday and today, I soldered the device, designed and printed the case of the device. It works, wow!!!

@ncollins And this is my simple capacitive button, just a button:). Beginning of this story was like this:... once I bought a Chinese capacitive button and was very upset with the quality...

@mfalkvidd said in NRF51-52 PA not support ???:

the return value of send() indicates whether the sending node received an acknowledgement from the next node. If the next node (the gateway unless you have repeaters) received the message and send() still returns false, it usually means that the acknowledgement was lost.
Maybe the PA makes it possible for the sending node to reach the gateway, but the gateway is unable to reach the sending node?

The network is simple, this node is nrf52 with an amplifier and a gateway with the nrf24 radio module with an amplifier. It would be strange if a gateway with an amplifier could not deliver ACK. Two moments, or I did a very bad control of the amplifier on the node nRF52 or in the radio driver itself, something is not working well, and may need some delay settings. If i send messages with an ECHO (soft ack) request, this works fine over very long distances. Hw ack does not work properly.

I can't win the battle against nRF5 radio modules with amplifiers. Added a foot control to the radio driver for switching PA LNA. This works, but if you try to get bool send (), it very often returns false, although the message is successfully delivered to the recipient, I tried changing the value in NRF5_ESB_RAMP_UP_TIME, it does not help. Someone tried to achieve normal operation of nRF5 radio modules with amplifiers in Mysensors?

@monte said in What did you build today (Pictures) ?:

Or do you mean that they are discontinuing 1.54" displays completely?

Yes, I mean that these displays are no longer produced. And it is better to focus on new ones.

@monte By the way, this version of screens is discontinued, it is better to develop software for new versions

FPC

Excellent handwork. I also dealt with such FPC conectors :), here are the correct FPC conectors - https://aliexpress.ru/item/32794813863.html

At first glance, need very little. Make the repeaters a little bit smarter.

Hi, everybody. Yesterday I made a case for my new device with an e-ink display 2.7. the Case turned out to be quite thin. The dimensions of the device in the case are 86.5 mm X 59.5 mm X 11.5 mm. The new device is a continuation of the project - https://www.openhardware.io/view/629/EFEKTA-TempandHum-sensorver-nRF52-E-Ink-display

@NeverDie This is not a very convenient update process, although it is incredibly fast. You need to download the archive with the firmware to your phone. In the nRF Conect app, you will connect to a mysensors device that has previously been switched to bootloader mode (secure bootloader). Next, you need to choose the archive with the firmware and accept the download. This is a research interest rather than a working option

@projectMarvin Most recently, I tried updating mysensors nodes on nrf52840 via nRF Conect (BLE). Incredibly fast.

@NeverDie My experience shows that the Chinese sensors that are sold on Aliexpress have a low quality printed circuit Board. When used outdoors, they may deteriorate within 1-2 seasons. Inside the house, in a flower pot, the service life is much longer. As for such sensors developed independently, the quality of printed circuit boards that are ordered through the services of jlcpcb, pcbway... very high.

— Andrew EfektaSB

Amazing project! I want to repeat it, but there is a problem. I can't find the T1 transformer where you bought it.

I don't remember exactly, but I think in my case it was due to using wait b sleep in before() and presentation(). This may be due to the power of the radio module.

Recently, I have faced exactly the same situation. Since this is no longer an isolated case, it means that the case is in the mysensors library.

Another one of my brand new device is ready, today I finished the case for this device. This is a motion sensor on the S16-L221D-2. Also added a temperature and humidity sensor, it can be sht20-21, si7020-21, hd 1080, perhaps something else, now there are many sensors in such cases. Powered by a "nuclear" battery 2/AA (14250) 3.6 V. Powered by a chip nRF52811. I added support for this chip to the sandeepmistry boards.

Soon this sensor will be available at openhardware.io

@monte said in What did you build today (Pictures) ?:

nice piece! Do you mean accelerometer for an encoder, or a physical one? And if the latter, what for is it supposed to be used?

I think the use cases quite a lot, I want to implement double tap. For example, there is a dimmable lamp with switching to cold and warm light. Here with the help of a double tap you can control the switch from cold to warm and back. In any case, I think this is a good extension of the functionality.

@neverdie Thanks for rating. Especially pleased, so as nRF52 for me began with Your those on this forum.

Another project of mine, the second revision is finished today and put to the test. This is an encoder with accelerometer, powered by nRF52811 chip (datasheet).

My new project is finished today and put to the tests. This is a continuation of my other project - Wireless Module for Capacitive Soil Moisture Sensor v1.2.

@scalz said in HALO : ESP32 multi transport GW/Bridge for Mysensors:

the webapp was great, but I converted it to native crossplatform app for better versatility&perf, so I can use one app for my devices, like Ethernet for HALO etc, or Serial for my other Janus gw dongle, bluetooth..
To be honest, I've not updated anything yet for a few reasons, like very little spare time for a public release + support for such "big" project. (easier to handle local projects).
Sorry, still no eta for the moment..

It is clear that there is not enough time. But this project can become popular. That's what's missing MySensors. ...This void must be filled.

Yesterday I finished my new project. This is motion sensor (S16-L201D) + light sensor (MAX44009) + temperature and humidity sensor (SI7020). Рowered by nRF52840.

Is there any fresh news on this project?

@franz-unix said in Printing enclosures with SLA printers.:

The "marble" case is very cool! The filament is easy to print or requires some special parameters? For example in this days I'm fighting with a wood filament, below

I did not print such cases myself, these photos were sent to me. But I can find out about the printing settings for the marble filament.

...The lamp looks cool

@neverdie said in Printing enclosures with SLA printers.:

Justs a thought, but now that mysensors has FOTA, then for projects which would have, say, 10+ years of battery life anyway, then for very little money one could simply acquire an assortment of silicone molds in various sizes and simply cast your project in polyurethane or polyester or some such epoxy rather than 3D print a box. I know that there's at least one guy, who builds sensors for deployment in wet caves, who has already been doing it for quite a while now. For outdoor sensors, they'd be completely weatherproof, and for indoor sensors, they would simply look cool. You could even get a nice smooth look in the cast object, just as you could with a box printed on an SLA printer.

What is this technology? Is it possible at home (in the garage:)) to make silicone molds? Have a description of the production process, an article or a video?

Since we're talking about printing, I'll post photos of a few more of my projects. These are completely new devices, they are still on tests. The cases were printed on the SLA printer, but then they were repeated by other developers on the FDM printer. As for the possible harm to health, vet and FDM printers are also harmful, ...specific types of plastics. It is enough to observe simple security measures and everything will be fine.

What resin do you use ? Can you share (by MP if you want) a screen capture in slicer to see how you print it (support etc).
Just bought a SLA printer and still learning, that would help me as I have similar enclosures to print.

Anycubic Resin. All my projects are always fully available on my github (Gerber, hull models, schematics, codes)

@franz-unix
This is made on SLA printer, but should normally print on FDM

@jeremushka said in EFEKTA Temperature & Humidity mini sensor:

Hello Berk,
Do you still have PCB board available for sales for this project or for the upgraded one with NRF5 ?

In about a week, I will post an updated version of this device. The changes will affect the attachment to the case. And it will be available for purchase.

An updated version of my temperature and humidity sensor with e-ink. Now on nRF52840. Now it is not a module but a device in the case.

Replaced temperature sensor sht20 -- > > si7020
Added accelerometer.

In the near future the project will be posted updated on the website openhardware.io

Video: https://youtu.be/T66y83lF-xg

My brand new device on nRF52840. It is a light and shock(vibration) sensor.

Two sensors are used, max44009 light sensor (1 ua) and lis2dw accelerometer (1 ua).

The light sensor measures in Lux.

The shock sensor has five levels of sensitivity.

Two modes of operation: main (working) mode and command reception mode.

The sensor accepts settings: the interval of sending data from the light sensor (in minutes), sending recalculated light data from Lux to watts per meter squared(on/off), the sensitivity level of the shock sensor(5 levels, 1 to 5)

Depending on which sensors are installed on the PCB, it can be used only as a light sensor, only as a shock sensor or both.

In the near future the project will be posted on openhardware.io

E-paper_2.13 nRF52840 bme280 Mysensors | Zigbee – 00:45
— Andrew EfektaSB

@magpern I think that perhaps the problem with the i2c bus. The revision of the chip. Try to disconnect the bus before going to bed and then initialize again.

@scalz said in What did you build today (Pictures) ?:

This evening I assembled another dongle (and a few other boards).
@nca78 as you asked, here is a pic during tests. Tiny dual rf dongle board, isn't it

This customization boards adafruit? I've customized the Board Sandeep Mistry.

@scalz How do you plan to use your dongle? Just as coordinator? or only as a gateway mysensors? Have you tried using it as a combo? zigbee quite unceremoniously uses the resources of the mcu.

@jeremushka said in Safe relay node:

Have you moved to nrf5 for this concept or finally decided to keep the current design which is working well ?

In the process on nrf52840, but most likely it will be a zigbee(although nothing prevents to make its software under Mysensors that's already available in the Arduino IDE for 52840). The problem with the Mysensors is to support slow and weak chips, the backward compatibility problem does not allow moving forward.

Hi, everybody. Modules nRF5 with RFX2401(signal amplifier) control the amplifier from the legs of the microcontroller, as a rule, r0.20 and P0.24.

Do I understand correctly that gain control is not implemented in mysensors for nRF5 modules with amplifiers???

It probably can be done from the sketch, including a strengthening of the:
digitalWrite(TXEN_PIN, high);
digitalWrite(RXEN_PIN, high);
send.(..
digitalWrite(TXEN_PIN, low);
wait.(..
digitalWrite(RXEN_PIN, low);
But there is also internal communication (which is formed inside, for example - find parent, registration..), the functionality of the repeater, how it should be?

Today I finished printing the case. Turned out to node with sensor bme280 and e-ink display, running on nRF52840 from SKYLAB

In one of the photos still have the sensor with bme280 working on nrf52840 from EBYTE. ...This is the previous project.

Can I use ST-Link V2 for this or do I need a separate device?

You can connect the programmer and TTL Converter at the same time. You can also do so - https://translate.google.ru/translate?hl=&sl=ru&tl=en&u=https%3A%2F%2Fmysensors-rus.github.io%2Ftroubleshooting_on_Cortex_MCU_in_Arduino%2F

On the SWD connector it says, TX and RX, how do I use them?

Via TTL Converter. The program must be enabled in the debug.

@magpern said in EFEKTA Temp&Hum sensor(ver. nRF52832 )+E-Ink display:

Any idea how battery can be at 60% on more or less fresh batteries... anyway, that is another problem.

Calculate the resistor divider. It is on the power Board. Perhaps you have mixed up resistors.

@bjacobse said in What did you build today (Pictures) ?:

Clever idea to use SN74LVC1G00 as while both inputs are same voltage it only consume ICC = 10uA (10 mircoA) in whole voltage range 1.65V -5,5V

Power consumption of the entire device in a sleep - less than 3 mircoA.

@sindrome73 said in What did you build today (Pictures) ?:

I'm sorry if I can, but what kind of sensor are you using to detect water ?? I would like to do something like that but with an Arduino pro !!

Used by SN74LVC1G00. Recently I was asked for this scheme in myssensor_rus telegram-chat. I drew it by hand in PAINT, I can offer it to you. I apologize, but nevertheless it is a scheme

@boozz It was just a photo session in various locations :).

The pcb, of course, will be coated with acrylic varnish. Stainless steel contacts are used. Conclusions do not have direct contact with the ground, there is a gap of about 0.5-1mm. Button holes are made from below, but look at how it is done in the photo. Well and places where leakage is possible, usually should not be wet, otherwise a mold and td. If there is moisture, then it is somehow better to eliminate :).

@boozz A leak of water in my memory occurred two or three times. Yes, this is not a common problem in the modern world. But sometimes it is enough once. And here it is important how this leakage will be quickly detected and, accordingly, the source of water supply will be blocked. And one more thing: insurance can not cover everything. One situation is when it’s a country house, but for example in Moscow I live in an apartment on the 6th floor, that is, there are 5 floors below with apartments, and I may have to pay for repairs in these apartments.

Now I have three sensor options: on a cr2032 battery, on a cr2477 battery, and on a 2 / AA (14250) battery with an amplifier.

The devices consume 3 micro amperes in a dream , on conventional radio modules they consume 7–9 milliamperes while the transmission is running, for modules with an amplifier of 24–26 milliamperes, and I can programmatically decide when I should turn on the amplifier.

@nca78 said in What did you build today (Pictures) ?:

what's the range improvement with amplifier ?
From my experience with nrf24 the amplifier + ceramic antenna was not giving great results.

A few months ago, when testing, I received about 200 meters of stabilized power from the power bank. While this device was tested for 30 metres. There are problems with receiving the delivery confirmation, the device is guaranteed to transmit, but does not receive the delivery confirmation(sometimes). I think it's linked to my gateway, it has the usual radio module nrf24l01+. Of course we are talking about dc-dc-mode

Pro version of water leak sensor, for very very hard to reach and remote places :). Version with amplifier.

My new micro-sensor water leak ready. Powered by NRF52832-CIAA

@kalina said in MDMSGate:

I am going to production a new batch of gateways, but before that I want to upgrade it. Does anyone have any suggestions for improving current version MDMSGate?

Hi, put away the black radio and put the EBYTE green radio :). The remaining problems do not concern HW.

ps/ Where have you gone?
