Esp32 Arduino Stable Release V1

#1

ExpressIf just released a stable esp32 v1 on github, I tried using it to compile and upload it to Esp32 chip and use it as BT Gateway and it works perfectly. Let me know if everything else works too.

Here is a installation instruction

Installation instructions using Arduino IDE Boards Manager
Starting with 1.6.4, Arduino allows installation of third-party platform packages using Boards Manager. We have packages available for Windows, Mac OS, and Linux (32 and 64 bit).

Install the current upstream Arduino IDE at the 1.8 level or later. The current version is at the Arduino website.
Start Arduino and open Preferences window.
Enter https://dl.espressif.com/dl/package_esp32_index.json into Additional Board Manager URLs field. You can add multiple URLs, separating them with commas.
Open Boards Manager from Tools > Board menu and install esp32 platform (and don’t forget to select your ESP32 board from Tools > Board menu after installation).
Stable release link: https://dl.espressif.com/dl/package_esp32_index.json

Development release link: https://dl.espressif.com/dl/package_esp32_dev_index.json

Thanks for the info !

@subrodey, I also complied OMG with BT only using official esp32v1 code. But I’m noticing that gateway disconnect from mqtt broker after some time, varying from minutes to ~5h and then do not reconnect, esp restart is required. Do you observe similar behavior or your gateway works without problems?

Best regards,

I only ran it for 30mins or so just to check if it worked… I will have to check and get back to you.

I’ve made some more tests today.

I’ve started OMG and I’ve put uptime and freemem reported by OMG via mqtt on chart (with help of OpenHAB and influxdb/grafana combo). Green line represents uptime, red: freemem. Breaks in green line means gateway lost connection to mqtt broker or wifi. When green line starts from the 0 = restart.

After initial tests I discovered, that OMG is able to recover mqtt connection, but only 2-3 times and then OMG is not accessible, not responding to ping - only reset helps :wink:
So I hookup OMG ESP32 dev board to computer and logged serial output.

I’ve searched for last error and found related to this issue topic on espressif github repo:

There is a long interesting discussion, with a solution to add to main loop delay using vTaskDelay(10); function.

I added it to main loop after line 663:

result:

    #if defined(ESP8266) || defined(ESP32)
      vTaskDelay(10);
      stateMeasures();
    #endif

Currently, with this modification, OMG is running for 3h35mins without connection drop. It’s too early to say that this a solution. Will report tomorrow.

BTW, I’ve enabled multicore for ESP32 in my case.

#6

I kept this on for 8 hours today… Went for work just returned and I found it to be workinng… Its reporting to the MQTT that its alive… However i notice that it might have taken 2 reboots in between. Having said that, its responding and there is no problem, beacons are detecting fine.

#7

Thanks for checking and reporting.

My OMG has just hung, afer 3h40m.

BTW, do you have multicore enabled? I will compile with disabled, no more ideas for now :roll_eyes: …

#8

I didn’t do any extra settings… Just uncommented other modules keeping the bt module only…

#9

I also have only BT module enabled.

Multicore is enabled by default:

One noticeable difference after turning off multicore is increased freemem reported by OMG from 15k for multicore to around 27k for multicore disabled.
Another test in progress…

#10

Hello,
Could you point us the version of omg you are using ?

#11

HI @1technophile
I’m running latest commit from github.
Compiling on Win10, Arduino 1.8.5, stock libraries (not from github repository), ESP32 devkit board V1 from DoIt.

Yesterday I reflashed ESP32 using unmodified code from github, only BT module, with and without multicore enabled. Results was pretty the same, OMG lost connection after ~30mins or so. I was not logging serial output, will do it today, but I do not expect different errors than Task watchdog got triggered. The following tasks did not reset the watchdog in time:

I have another ESP unit, but bare one (no dev board), will give it a try after soldering to some proto board to be able to flash it :slight_smile:

BTW, thanks @1technophile for great work!

Thanks!

#12

Hello,

Thanks for these detailled infos, it seems that other people are having this issue. Here is an issue to follow also :

#13

Hi,

I got all sorts of those problems with esp32. The last one being the gw disconnecting to the mqtt and reconnecting. A tcpdump showed something very strange: the mqtt sending a Fin (or Reset) packet and the gw trying to reconnect again. But I didn’t had time yet to investigate further.
I’m also reconsidering the use of esp32 as it seems that there’s a design/hardware flaw. If I understood correctly the esp32 use the same antenna/radio to both wifi and bluetooth, so if it’s scanning BT it can’t send/receive wifi?

#14

Yes and thats very annoying that one has to take care while doing anything with bluetooth and wifi together. Kts pretty flawed otherwise a powerful hardware poorly implemented.
