Hi, I've been using ESP-NOW on some project and I find it very easy, nice and secure. But I wonder, should I still use it for future project? It looks like it had a single launch in 2016 and no update were made. I know there's some people that would like/need new features like private broadcast chan...

Thank you!

So, to reflow the PCB, do you recommend using paste that reflows at a lower temperature than the listed 235 ~ 250℃, or is a paste that reflows at the same temperature is fine?

Hi, I'm getting a lot more into PCB design, but my work rate is very slow if I do everything by hand. I designed some custom PCB to fit an ESP32 WROVER-E on it. In the manual , it says the absolute maximum rating is 150°C (storage temp). If I put a PCB with a WROVER on it and I reflow the board at 1...

I manage to make it work a while ago. I don't remember how I solved the problem. I think it has to do with the call order of functions. Here's the setup code (Slave and master don't have the same meaning for me): Note that you could use memcpy instead of loops. Master Side (Slave is a custom Object)...

Learning how the J1939 protocol works would be benificial for you. Documentation is pretty hard to find, but here's some basics : J1939 has extended bit addresses (29-bit) compare to CANOpen or OBDII. Each address contains a standardized type of information for vehicle. The address contains a PGN nu...

Hi, I want to make a private network. I have 2 ESP32 talking to each other with unicast messages but broadcast messagegs can still be received. I'm afraid that someone could flood the network with broadcast messages and jam the ESP32s. I already filter the messages when I receive them, but the ESP32...

I guess if you want a quick hack you could add an ESP32/ESP8266 which bridge one of the esp on the network via bluetooth, then send the information to your local network, which could be controlled by your phone. Or, I don't know if it's possible, take ESP-NOW messages and send it directly to a wifi ...

Hi, Do you have control over the device that is sending the CAN messages? The reason why you don't receive 1.3 is because the sender is not sending 1.3 Usually, REAL numbers in CAN protocols have 32 bits (4-bytes), unless there is a "per bit" value like in J1939/OBDII protocols. 16-bits "REAL" are r...

Hi, sorry for double posting.

Anyone can help me?

Depending on how critical is your application, I would recommend to enable One-Shot mode ONLY if it is necessary.
