Esp32 ble mqtt

Esp32 ble mqtt

Released version of ESP32 env 1. After how much time the esp is disconnecting? Was it connected to the serial monitor to have some traces? So I did a git pull and tried the new 0. I didnt upgraded the arduino or any other library at least, not that i know.

Did I missed something? Is it possible that the arduino IDE updated a library automatically? And LWT has quite a few entries and afterwards total silence. Some questions so as to investigate. I suppose that in both conditions the esp is located in the same place.

When you are powering the esp32 without serial monitor, is it by the usb port? Is the board standalone or with sensors? Did you try with different boards? ESP32 without computer connection is located in the same area as the computer less than 1 m radius.

I used two ways of powering: one with a 2. Used with an USB metering, the power supply gives a stable 5. Then, after a while, the gateway is offline now there are 12 hours since last activity; sometimes it would start again even after a long pause.

The next step would have been to try to disable multicore but I think there is no need for that since the board works fine now connected to a 5V USB charger. When working fine there was 0. The following tasks did not reset the watchdog in time:. Github Devices Community Docs Blog. Bluetooth gateways. BLEDevice::init The wiki is updated with the good links.

I can now confirm that finally it is working! At least for 24 hours Thank you! I moved on to a Pi Zero W solution. Will try this again some time…. I compiled as described but esp will disconnect from WiFi after a while.

How did u proceed, wanna move to raspi too as esp seems unreliable and unstable for the moment. What about the ble temp sensor? Works also with it? PetricaM September 22,pm Hi PetricaM Some questions so as to investigate. Could you give the history of traces in the serial monitor?

How to Connect ESP32 to MQTT Broker Using CloudMQTT

I tried windows a bit less 0x, 0x90 and then the wifi connects, but not that fast. Without ble scan, wifi connects faster, so it seems like a bandwidth sharing.

I am expecting similar issues in my case aswell, so I am planning to keep a monitoring task which should monitor the activities, network pings for ensuring network is working, if BLE is not giving any scan result for few minutes then something might have happened to it, so I may need to reset the ble part of the code. Seems like the ble part is not that matured. Jump to. Who is online Users browsing this forum: Baidu [Spider]ecc espflorent92francis2 and 57 guests. All times are UTC Top.

Skip to content. I would really appreciate any help possible to get this stable running and just doing the above job. Do you have crash logs, backtraces,? A quick glance over your code: It seems you try to send the mqtt response from the gat event handler, right? From memory, this runs in one of the BT tasks, not in the main task where you have started mqtt. I could be wrong don't know the mqtt code that wellbut this probably leads to concurrency issues on the MQTT side of things.

It's better to let the BT code dump its data into a FreeRTOS queue or something, then read the data from the queue in the main thread to send it to the mqtt code there. Jump to.

To use MQTT, you need a broker. You can use the preceding links or go directly to MakerAdvisor. Copy the umqttsimple library code into it. You can access the umqttsimple library code in the following link:. View raw code. In the following variables, you need to enter your network credentials and your broker IP address. The counter variable is simply a counter to be added to the message. In the main. Copy the following code to your main.

The first thing you should do is creating a callback function that will run whenever a message is published on a topic the ESP is subscribed to. In our callback function, we start by printing the topic and the message. Basically, this callback function handles what happens when a certain message is received on a certain topic.

This function is responsible for connecting to the broker as well as to subscribe to a topic. This way, we can access these variables throughout the code. These variables were set on the boot. This function prints a message to inform that the connection was not successful. We wait 10 seconds. Then, we reset the ESP using the reset method.

MicroPython – Getting Started with MQTT on ESP32/ESP8266

From now on, the code will call those functions to make things happen. The first thing we need to do is to connect to the MQTT broker and subscribe to a topic. We use try and except statements to prevent the ESP from crashing in case something goes wrong.Only tracking distance and presence of Bluetooth devices?

OMG supports indeed presence detection by scanning BLE devices and reading of devices dependent values from the following ones temperature, moisture, humidity… :.

Maybe we could try to reverse engineer their protocol, would you be interested in participating? I would like to, but I need to know what to do at least, to say yes. Maybe this is relabeled Xiaomi product. Any instructions on how to do this links please?

Demo 14: How to use MQTT and Arduino ESP32 to build a simple Smart home system

This is my first time when I used ESP I just loaded precompiled files into ESP Played with ESP a lot. OK, All errors are cleared, learning with Platformioand now Im getting even less information from the scale. I advise you to let it scan for at least 10 minutes with some weight on it and see if it publish some service data.

And how to? Because when scale connected to the android app it uses a pin code. I want to add to your discusion.

Easiest ESP32 BLE (Bluetooth Low Energy) Tutorial - Arduino

I have it!!! The number of service data is in little endian format. Splitting the number in pairs, and choosing the 2 and 3 pair you can get the weight. It is wide explained in the post, but in summary the idea is:. Just to know, you think that can be integrated to OMG in the future? Or better I make a script that does the calculations and conversions and re-publish the results. I will integrate it to OMG.

Maybe I will need further details or tests if possible. You can contact me at pavon87 at Gmail dot com Thanks Florian!I appreciate your tutorial, yet there are some mistakes that should be clarified, the most obvious being your statement: "Topic: the message that is transferred on network" A topic by far is not a message itself but rather a category for a message.

You should possibly consider a topic string as part of a message object from a sending client perspective. Thank you very much, I updated it.

Skip to content. I would like to publish the sensor data to mqtt broker. Below is my programming. And I modify by myself some took from this forum discussion.

My ESP32 able to connect and get data from the sensor module. But I have a problem : 1 The result didn't change. Even my program I make it will go get new data each second, the result is always same. My program not going to get new value? Full result as above, will have 40 character I don't know how to call.

But the problem is, the result will stop until "0".
