[Bug]: esp32 DevkitC v4 Looses Connection

[Nubi123bty]

For some reason, the Windows Client is unable to connect to the ESP, as soon as it is found and an attempt to connect is made it loses the connection to the board over BT.
this is the error created by the player:

Thank you for submitting an issue! Please, help me investigate your issue. I'll need more detailed info, such as

• which version/branch of firmware you are using
• what device you are building
• bHaptics Player version (Can be found in Settings menu)

Also, please, try switching to v0.1.2 version, which is confirmed to be working great with the following steps:

[Nubi123bty]

thank you for looking into it,
Building the tactx40, but having the same issue with any other Build on the devkitC V4, Tried 4 different Boards, I am using the 1.2 as recommended, the Player version is 1.8.2.2, had the same issue with the previous release,
the connection is breaking off several times until after 10 to 20 minutes there seems to be a connection.
this is the final serial output on the serial port when connected.
i also tried to downgrade ESP32 Library version to 2.0.0 while testing, with the same issue.
Reinstalled and reset the player, EEprom is erased every time before another Version is copied onto it.
clearly there must be a mistake on my side since no one seems to have encountered it, maybe my environment?

Have you tried connecting to ESP from your phone? Or Meta Quest of you have one

I have an idea why it might happening, I'll lol into it tomorrow

DFU is responsible for firmware update, and presumably bhaptics player trying to update firmware (?). I'll try bumping version to latest one and see how it performs

[Nubi123bty]

the mobile device paired right away.

[leon0399]

I've bumped the firmware version to prevent it from trying to update, let's try a new version. Don't forget to checkout the latest master branch

[Nubi123bty]

no, still the same problem, only after many attempts is the connection established, I just recognized that the Second PWM on address 0x41 is not getting any signals, does it have to do something with this issue?

ok one thing I was able to test the connection on Oculus Quest 2 (SW-Ver.: 415550688) Bhaptics Oculus Player Ver.: 0.7.14, Firmware on ESP Tact X40 V1.2.
I can't connect with the Tact X40, The Gloves I made on the ESP32 Devkitv1 Work fine. no error message is produced.

[leon0399]

The Gloves I made on the ESP32 Devkitv1 Work fine

By gloves, you mean "Tactosy for hands" compatible device?

[leon0399]

I've just verified that it works correctly on the latest master branch, bHaptics Player 1.8.2.2
Consider joining our Discord, we've been discussing possible causes of this problem, one of them is the bad quality of either the Bluetooth adapter/dongle or the ESP chip itself and how to distinguish good quality ESPs from bad ones

[Nubi123bty]

Thank you very much, for your time looking into it. I will try to get another, than from AZ-Delivery, to try it out.

[Nubi123bty]

is there a possibility that the BT draws too much Power from the esp when connecting? what version of the ESP itself are you using or what brand is the Devkit?

[leon0399]

what version of the ESP itself are you using or what brand is the Devkit?

I'm using this ESP32 devkit board from AliExpress: https://aliexpress.ru/item/32864722159.html?sku_id=12000028745117645 (ESP32-D CH9102 variant)

I've also started collecting a list of trusted links on these two pages: https://openhaptics.github.io/docs/hardware/mcu and https://openhaptics.github.io/guides/face-interface/quest2-esp32-breadboard (don't mind guide itself, it's not complete)

[Akluma]

I have same problem.
