PROBLEM DESCRIPTION

I am trying to get the DFRobot AS3935 ((https://www.dfrobot.com/product-1828.html)) to work on Tasmota.
It's hooked up to an ESP32 (M5Stack Atom Lite).

I can see it in the console show up as an I2C device:

22:43:50.772 CMD: i2cscan
22:43:50.801 RSL: RESULT = {"I2CScan":"Device(s) found at 0x03"}

I configured the IRQ Pin and can confirm that the i2cdriver48 is enabled. 'i2cdriver' shows it, manually ran "i2cdriver48 1" just to make sure.

The problem: It does not show up any other way. I don't see the measurements on the main UI screen and none of the as3935 commands work. Seems like the driver isn't 'registering' to the device somehow.

(not 100% sure which part would be interesting here, but this is a boot log from yesterday. I guess the interesting part is the fact that it's missing the as3935 driver saying something)

TO REPRODUCE

Connect DFRobot AS3935 to ESP32 and configure I2C and IRQ Pin

EXPECTED BEHAVIOUR

I would like to see the sensor data show up, but aside from the i2cscan it does not

What barbudor suggested was to open a discussion, not creating an "issue" which is for bugs. What you have looks more like needing help making it work. As indicated in what I posted both on Discord, and in the other thread, I had no trouble getting Tasmota to recognize AS3935 and report values. Did nothing special, just the recommended wiring and Tasmota config.

Happy to move it to a discussion, but given that the I2C communication seems to work and I can't see any of the usual issues (not using a sensors build, not having the driver enabled, not setting up the IRQ pin) I would suspect some sort of issues during the initialization of the driver that might be particular to this DFRobot build of the sensor?

Can you set WebLog 3 and restart tasmota (restart 1)
The AS driver may put some more details at boot

That output is already in the original post. Sadly nothing :(

Ok, I will build a more talkative version of Tasmota32 with more logs to track line by line

Here you are, based on latest dev branch
@sfromis could you please test also with this tasmota32 version so we can compare logs ?
thanks
EDIT: test binary removed

Interesting:

I think this part is the important part:

00:00:00.575 AS3935Detect: let's try to find out chip
00:00:00.581 AS3935init: reset done
00:00:00.582 AS3935init: false afe_gb=0x2E

I guess that's in here:

bool AS3935init(void) {
  AS3935Reset();
  uint8_t afe_gb = I2cRead8(AS3935_ADDR, 0x00) & SETREG00MASK;
  if(INDOORS == afe_gb)
    return true;
  return false;
}

So instead of "define INDOORS 0x24" it returned "0x2E"

The whole thing:

Thanks a lot
Let me get that datasheet to understand that afe_gb value

I wonder if this is what their 'official' library checks against over here:

https://github.com/DFRobot/DFRobot_AS3935/blob/master/DFRobot_AS3935_I2C.cpp#L343-L354

uint8_t DFRobot_AS3935_I2C::begin(void)
{
  uint8_t buf[2];
  Wire.begin();
  Wire.setClock(400000);
  DBG("i2c init");
  if(readReg(0, buf, 2) == 2){
    DBG("return");
    return 0;
  }
  return 1;
}

(Just a guess... I'm not that great when it comes to reading these)

Ok, so the driver sends a PRESET_DEFAULT and from the datasheet, the AFE_GB (gaib boos) should be 0x24
So

either we don't leave anough time to the chip to set itself to the default
your chip has different default values for some reason (different version, chinese clone ?)

Here is a test version with 10ms delay after reset, instead of 2 ms (I have not found in the datasheet any details on the expect reset delay so that is just a guess)
If not, we could try a larger window value for that test

EDIT: test version binary removed

None expected today. I wonder if any of the commands would show that it's communicating correctly?

AS3935settings will read the settings in the chip (and in Tasmota)
You can change some chip settings and see if they are taken into account
AS3935disturber with 0 or 1
AS3935setnf set noise floor 0 to 7
AS3935setrej set spike rejection 0 to 15
etc ...

So your problem may be a deffective module
Do you have another one ?
May be try another source than DFrobot ?
I understand that's not the cheapest sensor ...

Yeah, I'll probably have to take a look at that.

I think my next step is to hook it up to an arduino or raspberry pi and see what it does with their 'native' code :(

ok, i have found a User that have also a issue with the DF-Robot AS3935 and the ESP32:
https://www.komputer.de/zen/index.php?main_page=product_reviews_info&products_id=509&reviews_id=57&zenid=ai0u7f0r6q1h7b5rka6tum1480

(Its' a German comment).

I'm not a Hardware Guru but i found in the Schematic from DFRobot, that the Pullup Resistor from SDA is missing.
Could that be the Issue for the communication Problem?

Here the Schematic from MOD1016:

and here from the DF-Robot Modul:

It looks like that the internall Pullup resistors are too weak:
https://esp32.com/viewtopic.php?t=379

Maybe someone can answer with more experience with the ESP32 and I2C pullups...

+++ Eagle-Eye +++
Better use on Front Side
PIN "+"(VCC) and
PIN "D" (SDA)
The Numbering on Pictures is not clear. it's a risk without measurement!

ok, great!

there are 4 measuring points at the backside of the module but i can not determine the order and labeling:

numbering as in the Schematic:
T1-VCC
T2-SDA
T3-SCL
T4-GND

In the best case, it is like the same as at the frontside, but beware, it must not be the same. Please measure out the points.

then do a 10k resistor between T1 and T2.

good luck!

The board overview from their docs suggests a different numbering, assuming that the pads match the socket on the other side.

Hey, do you have any update regarding this issue?
I have very similar problem with GY-AS3935 and ESP32, however I'm not using Tasmota.
My sensor can be found via I2C only from time to time, when it gets configured properly, reading it's configuration often returns wrong data.

Have you managed to fix that problem?

5 replies

barbudor Oct 19, 2022

If you read the above discussion you will see that the problem was solved by adding a pull-up on SDA which is apparently missing on some models of boards

szerwi Oct 19, 2022

@barbudor Yes, I saw that, but there is no confirmation that it actually solved the issue. Thanks for rectifying!

I broke mine and haven't bought a new one, so indeed can't confirm :)

CrazyHenk44 Jul 27, 2023

Still no confirmation anywhere. I'm not an hero with understanding the diagrams, but i just solder an additional 10k resistor between 1 and 4 and leave the rest the same?

barbudor Jul 27, 2023

@CrazyHenk44 That's what the discussion is pointing. Not owning such board mysef, I can't confirm but this is a safe modification to do without any risk
Preferably a 4K7 which is the I2C standard

Hi, I bought DFRobot SEN0290 and tried adding 10kOhm resistor on VCC and SDA. It didn't helped. I tried also with different address switch configuration Device isn't recognized on I2C bus. Other sensors are visible.
