Thanks a lot for these very detailed explanations! Now I understand what I see, and realise that my experiment was working only because: 1) ESP32 uses little endian 2) I was only using small values for rev. In that case, I simply changed the positions of my fields in the struct, putting the int firs...

Hi, I am playing with several ESP32s linked together via a CAN bus. The simple prototype I have made is working well with 3 nodes, they are exchanging messages successfully. For the ones who don't know about CAN, the frames exchanged can contain a maximum of 8 bytes of data. For one specific type of...

Unfortunately, I didn't find a way to make this work.

I have found a workaround, by creating 2 distinct HTTPClient variables. But I still would like to understand what is happening

Hi, I am stuck with something that seems pretty simple. I have an ESP32 linked to my door bell. When someone rings at the door, I want it to post a message in a telegram group, and to trigger a scenario on my home automation system. These 2 actions are performed via the HTTPClient library, with the ...

So I made some experiments. I can detect the BLE devices around, and get their RSSI to determine if they are close or far. As I had a high number of devices around, I filtered for the Apple devices (manufacturer data starts with 4c 00) but the problem is that I cannot filter specifically for iPhones...

Thanks a lot, I will play a bit with it, and will report here about the results.

Thanks for your reply. But if I understand correctly, the esp32 would be in receiver mode, which means that the iPhone would be in sender mode, and for this I need an app running all the time in the foreground... Or would the esp32 "see" the iPhone even if no app is running? Concerning the pairing, ...

Hi, I searched a lot on the web but didn't find any clear information about what I want to do, so I decided to create a post here. I would like to put in place an ESP32 in a room, that would detect the proximity of a specific iPhone, and send an HTTP request to my home automation system to set the h...
