network.hostname() seems useless... does mDNS work?
Current target: esp8266
On the official docs:
https://docs.micropython.org/en/latest/library/network.html
network.hostname([name])
Get or set the hostname that will identify this device on the network. It is applied to all interfaces.
This hostname is used for:
Sending to the DHCP server in the client request. (If using DHCP)
Broadcasting via mDNS. (If enabled)
It seems to me that there are no references in the esp8266 pages regarding this function:
https://docs.micropython.org/en/latest/esp8266/quickref.html
I tried to use network.hostname() both before and after the wifi initialization (AF_STA mode), but it doesn't seem to work.
With a packet sniffer, enabled in promiscuous mode on the wifi interface, I see the packets (also broadcast and multicast) of other devices but not the packets that esp8266 should send to publish its hostname.
I'm specifically interested in mDNS.
I am available for any test and feedback.
docs: network hostname on different ports
It seems on esp8266 this function is useless:
network.hostname()
Please see https://github.com/micropython/micropython/issues/11450
Does anybody confirm this?
If it is unsupported, I think
- It has to be documented, ASAP.
- It would be nice to fix: remove the function from the ports where it doesn't do anything or leave it but reporting that it doesn't work.
On how to report to the caller of the function, should a NotImplementedError be raised?
