I have seen examples for changing the hostname like:

WiFi.hostname("MyESPName"); // change name for router detection

Although this compiles correctly, it doesn't work. I can put this in the Setup(), before any WiFi related command or after, and it makes no difference. No matter what I try, the router still sees the name as "ESP_xxxx".

If you know of a way to change this that works, please let me know! I can't be the only one that is having this issue with the Arduino IDE. Thanks!

I was really confused with the

WiFi.hostname("MyESPName"); // change name for router detection

Because it didn't work. I'm sure it changes something but not what I needed. I was using the OTA sketch.

What worked for me is the following. Currently I use the last three digits if the IP address to name my modules as I can more easily identify them that way. Much better than the last chars of the MAC address.

The function strToChar does not compile under Arduino. Is there some other include that is missing?

I changed the casting so that it compiles without a warning using this:



I put this in the Setup() before the WiFi.begin and it does not change the name that my router sees. I tried moving the code after WiFi.begin and that also did not work. Do you have a simple project that will compile and show this actually working? Thanks!
