💬 HALO : ESP32 multi transport GW/Bridge for Mysensors

So far (but not digged a lot) i've only seen PA smd modules with ipex (but would be better if i could fit sma) or chip antenna (lol). Are you thinking to an other reference, or have a favorite module??

This work quite well with the IPX PA+LNA SMD modules

[Nca78]

@scalz I have those with chip antenna , soldered one board but didn't try it yet.
I also noticed this week that my local shop sells low power smd version with a PCB antennad design similar to the one used in ESP12F which is pretty good. I will order next week and test the range. They have the same pad footprint than the SMD PA LNA (GND pin moved opposite side from VCC) so I could be interested in keeping this footprint for those leaving in appartments and that don't need a long range.
I have a 130sqm appartments and I have few packets losses only despite very thick (30cms) concrete walls, using only basic nrf24 modules at the moment. So I will only need a bit of improvement to have perfect reception everywhere, if it can be done with the 3€ PA LNA with chip antenna or 2€ module with improved antenna it's great for me.
Blasting my messages to the 350 other appartments in my building doesn't sound like a safe option :D

[scalz]

thx for feedbacks.

@Nca78 oki. noted! To be sure, are you talking about these modules ?

[Nca78]

@scalz yes these are the ones.
And they have versions with external antenna connectors also, amplified and even non amplified.

[gohan]

They look genuine, where did you buy them?

[scalz]

@gohan
yes in theory they are genuine as they claim to buy the chip from Nordic. you can find those modules at ali or ebay. just search for the module ref you need.

[Nca78]

@gohan so they claim but at less than 2$ for one module I have doubts...
Check on the website they have a "sample" button or "order sample", it links to the module on their ebay shop, they use it for selling samples.

[gohan]

I think I'll still go for the Itead ones then

[gohan]

@scalz how is the project going?

[ranseyer]

Hi Scalz,

is it possible that you share the schematic ? Im Interestet mostly which Pins you uses to the "? mysX ?" Connector...
Greetings

[mfalkvidd]

@ranseyer if you mean the mysx connector itself, the pins are available at https://www.mysensors.org/hardware/mysx

[ranseyer]

@mfalkvidd : Thats correct, but im working on a pin assignment (for STM32 and) ESP32... Mybe its a goot idea to open o new thread for that...

[scalz]

I'll update asap my projects (new designs&more features, softwares etc.). I've been quiet but not inactive :)
I just need to rethink how I'll share all of this because there is quite lot of stuff.. (interesting imho). I hope you'll like them.

I agree with mfalkvidd, you can take a look at myxs definition. Your pin assignment doesn't have to be the same as mine.. these mcus (STM32 and ARMs, esp32 etc) are flexible, you should check the datasheet ;)

[berkseo]

Have you tried some of the examples to run the gateway? I recently tested ESP32

Sketches in examples do not work in a sheaf of ESP-RF24

Board downloaded from git hub Expessif

I tested on NODE MCU32S

[mfalkvidd]

To anyone trying to help @berkseo: the problem has already been solved in a separate forum thread. You can access the solution at https://forum.mysensors.org/topic/9510/esp32-gateway-pinout

[heinzv]

I'm not sure if this helps, but I can say, that the MySensorsGateway code works with ESP32 in principle.
I have tested it with at least two different boards. One ESP32 from Heltec with an RFM95 (SX1276) on-board and one barebone board @ranseyer and myself have designed (picture attached).
For the barebone which we have designed, I used the board definition Nodes32s in Arduino. The only thing which I have defined in the Gateway-Project was the CS/NSS (chip select pin) as it is not where the code expects it as default.
So I had to add (bold line):
// Enables and select radio type (if attached)
//#define MY_RADIO_RFM69
#define MY_RADIO_RFM95
#define MY_RFM95_CS_PIN 17

After that, I got success messages in the serial output:

I know, you don't use the RFM95 but I guess it should work also with other radio's

board I use from ranseyer:

I know I don't give news about this project.
So, maybe I should show you few pics, just in case.. ,)

First, I prefer to say, we can't share code for the moment..not very release-able.

We are using completely custom code for this project. GW code is quite big, mysensors is an experimental version (sort of "v3"). Plus for all the features, sometimes it can need some tweaks in esp32 libs etc. for the moment, sw is still tied to this project&hw.

That said we have lot of neat stuff working, hw choices changed a bit too.

Here we go:

• asynchronous
• http webserver + websocket server
• mqtt client
• transport bridging
• embedded webapp for UI
• etc.
  Well I cannot make a list for the moment, there are lot of features.

Concept is autonomous simple network without need of a advanced controller, or when linkto/controller is down, that you can control and debug from your phone or computer. With step by step configuration, inclusion etc for easy getting started.

Pics of the app ?? Teasing ON!

The app is realtime and very reactive. Responsive and mobile friendly. This is a single page app. written with Vue, no jquery. lightweight Bulma CSS

I started to make some widgets.. there are also multiple filters for dashboard.

It will also be possible to get infos about network, rssi, stats etc

Lot of settings, I let you imagine them.. there are a few dedicated steps by steps too, handy for starters (like my family, friends..).

It's also possible to see all logs, downloading them, updating app files etc.

Teasing OFF, I prefer to keep some other nice features to show you later :stuck_out_tongue_winking_eye:

don't ask for a release date plz, we're busy on lot of projects, but we'll try to do our best! stay tuned :)

@scalz
Wow 8)

[heinzv]

I'm also impressed, I'll certainly observe this project(s). Especially because the base of my nodes is also ESP32 (see picture above)
:clap:

[alowhum]

@scalz Wow, that's amazing!
