Possible to set Disconnect Timeout or get Last Bluetooth Update Time? about bluepad32 HOT 8 OPEN

Perhaps there is a way to ping the "db" (how strong the signal is)... and report that feature.

A "ping" or "keep alive" also, but I don't know whether Bluetooth has that feature

from bluepad32.

Yeah... I have a car with xbox controller, works as well, but when disconnect, by code of Bluepad32 have a timeout of 20s, then if I'm pressing to accelerate and lose connection, my car continue forward movement and crash in any obstacle :/
I try to find some way to do that manually but don't have how, no true feedback from bluepad.

yes, I should provide a way (assuming it is possible) that the controller might be out-of-range soon... I need to investigate it a bit more

I recommend using something like this:

in your main loop, you should receive a "gampad event" almost everyframe.
if you don't receive an event in 250ms, then either:

• no new events were received (buttons/axis are not being pressed)
• or the gamepad was disconnected/outside the range

in any of those cases, just turn off the motors, etc.

Hi,
I'm facing a similar issue using 8bitdo Controller.
Can you explain more specific how to implement such a "gamepad event" flag which could be used to react on?
thx

@JochenKr See this comment. It explains how to use it: #42 (comment)

Thanks. Tried it and it improves the situation a lot. Still I need to add some delay like 2s, because the response from update() seems to be often false. But this should be good enough for my case

from bluepad32.

I didn't understand the delay that you need to add.

Take a look at the updated Sketch to learn how to use correctly:

https://github.com/ricardoquesada/esp32-arduino-lib-builder/blob/release/v4.4/bluepad32_files/libraries/Bluepad32_ESP32/examples/Controller/Controller.ino

search for hasData and update in that file... those are the two new functions added.
