Re: Dynamic lambdas pass to attachInterrupt


I'm not sure a lambda really lends itself to making an ISR. The interrupt has to be attached to each pin you would want a response from, so you will have to call attachInterrupt multiple times in any case, which would mean multiple copies of the function resident in memory. Maybe you just want to ...

Dynamic lambdas pass to attachInterrupt

Hello,

I would like to have a common function that receives any PIN number as argument, then create a common ISR using attachInterrupt on that pin.

I decided to use lambda for dynamic purpose. However, I got stucked at how to pass the pin number to callback function.

For more details, please see ...

Re: ESP32 SPP connection dropped after 3 seconds


Hi tanmath, yes it can be captured. I followed the instructions in this Stackoverflow answer .

I'll copy them here in case the link ever goes bad:

To capture Bluetooth traffic using Wireshark you will need the BTP software package, you can get it here . Install the package and find the files ...

Re: ESP 32 Keep rebooting/resetting

Firstly, try Blink example if it works. After that, minimize your code to check where the problem is. Post your code if possible.

Re: ESP32 SPP connection dropped after 3 seconds

Since you already figured it out, I'm here to ask for your help. Could you show me how to configure Wireshark to capture Bluetooth packages? I'm using Bluetooth classic, can it be captured? Thank you.

Re: Dual SPI on ESP32-WROOM-32E

Since CS, MOSI and SCLK are working on your scope, I doubt the issue is from your stepper. I suggest removing SD card out and check only stepper if it works firstly.

The requirement is that, esp32 first scans and pairs to bt headset then transfers the audio source.
After that, it will need to automatically reconnect to headset in either ...
