Re: arduino-esp32 IDF component build failure

The codebase between the SDK and this Arduino component have deviated too much. For example, the ethernet component is now named esp_eth. I started to pull all of the headers out of the SDK and update those in the Arduino component but it is just too tedious to do manually. All of the needed include...

Re: arduino-esp32 IDF component build failure

I have also tried building with Derrick's modified version and get the same thing as the official version. "Failed to resolve component 'ethernet'." This would have to break a ton of projects that incorporate Arduino libraries.

Re: ESP-NOW specifics [WIFI-2245]

The three ESP8266s I tested with had never been connected to an AP or anything else. I took them out of the package and flashed my ESP-NOW code on them and they all worked and could send and receive to one another, apparently using higher channels. This was ESP-NOW only communication. On one of them...

Re: ESP-NOW specifics [WIFI-2245]

FINALLY got this sorted out. I'm not sure if this is a bug in ESP8266 libraries, or a lack of documentation or proper example code, but the problem is that the ESP8266 was operating in higher channels that put them outside the frequency of the channel the ESP32 was operating on. In code for both ESP...

Re: ESP-NOW specifics [WIFI-2245]

I've just about exhausted everything without success. My software is dumping the Wifi MAC address which I see in monitor. I can then use Wireshark to see packets from the ESP32's MAC address, and the packets obviously contain the data I am sending. With the ESP8266 I do the same thing, but Wireshark...

Re: ESP-NOW specifics

I still don't understand what is going on, but have discovered one thing. Using Wireshark, I can see the ESP-NOW broadcast transmissions by the ESP32. However, I cannot see any network packets from the ESP8266 modules with Wireshark. Again, the ESP8266s can communicate with one another fine using ES...

Re: ESP-NOW specifics

Do you have any guidance on how to sniff ESP-NOW packets specifically? I tried Wireshark on both Windows 10 and OSX and could not see what appeared to be ESP-NOW packets from the known working ESP8266a. I tried the Mac / OSX because Wireshark on that works in monitor mode which is supposed to show a...

Re: ESP-NOW specifics

Thank you, my testing today with 3 units also showed that they manage their traffic and do not transmit over one another. Is the ESP32's ESP-NOW compatible with the ESP8266? I have 3 ESP8266s communicating properly with ESP_NOW, and finally received an ESP32 today. However, the ESP32 cannot send to ...

ESP-NOW specifics [WIFI-2245]

I've read all the material I can find on the ESP-NOW protocol, but I still have some unanswered questions. As an aside, it appears I registered only for the ESP32 forum and not the ESP8266 forum, but I imagine that the protocol itself (although not necessarily the way we programmatically access the ...
