Re: Using RMT to decode protocol

So I created the reader, and uploaded it here: https://github.com/morcibacsi/esp32_rmt_van_rx Is there a way to rename the topic to include the term VAN bus, like "Using RMT to decode VAN bus protocol" I could not find a way. Very cool project!! I wonder if this code could be adapted to decode the ...

I am in the same boat. Did you get this to work? If so would you be willing to share your string? Thanks!
No, I was never able to figure it out unfortunately... :(

anyone else have ideas?

What I would like to do is have the ESP32 setup as a WiFi access point , and then you can connect to it with a laptop or phone and choose/upload a firmware .bin directly from the lapto...

Storing Jquery as a C-string

Had a quick question regarding the "OTA web updater" program. I would like to be able to use the web-based updater function without internet access, using the ESP32 as an access point and not a client on an existing network. Basically, I would like to have a firmware bin stored on my phone, have the...

Re: Additional current draw in Deep Sleep+ULP if WiFi.begin() called

This is a regression in recent versions of ESP-IDF. We are working on a fix. For now you can add a call 'adc_power_off();' (from driver/adc.h) right before entering deep sleep. Excellent! Thank you. Do we have to call adc_power_on(); when the ESP32 wakes up from light sleep? Or is ADC re-enabled wh...

Re: Additional current draw in Deep Sleep+ULP if WiFi.begin() called

Ive noticed this problem too... In my program, if I initialize WiFi and then want to put the ESP32 in light-sleep, it uses 1.5-2mA more than if I never initialized WiFi at all. Ive tried calling: esp_wifi_stop() WiFi.mode(WIFI_OFF); esp_wifi_set_mode(WIFI_MODE_NULL) None of them COMPLETELY shut off ...

Re: CAN-Bus API multiple filter configuration

Why cant you just do a simple software setup?

ie

if (rx_frame.MsgID == 0x123)
{
read the message in and do something with it.
