The nodename returned by uname seems to be hard coded.
To be compatible with RPi and PC it should specify the network hostname.

There should be a way to change the nodename and use that as default for network hostname.

Test code.

from uos import uname
import network
uname()
(sysname='esp32', nodename='esp32', release='1.13.0', version='v1.13 on 2020-09-02', machine='ESP32 module with ESP32')

wlan = network.WLAN(network.STA_IF)
wlan.active(True)
wlan.connect(ssid, password)

wlan.config(dhcp_hostname="lora32-01")
wlan.config('dhcp_hostname')
'lora32-01'

NOTE: nodename should be same as dhcp_hostname: 'lora32-01'

uname()
(sysname='esp32', nodename='esp32', release='1.13.0', version='v1.13 on 2020-09-02', machine='ESP32 module with ESP32')

Thanks
