I am having problems to set up an accesspoint on my raspberry 3.
The purpose is, that I want a MQTT server runnig on the pi and other devices should connect to the pi. I need no bridge to the internet or similiar things, just a connection between my mqtt server (pi) and the clients. The whole setup needs to be portable, so whereever the pi boots up a SSID should be visible and accesable.
I found these two links:
I started with a fresh raspian stretch image. Like suggested I installed
hostapd and made the following changes:
interface wlan0 static ip_address=192.168.4.1/24 static routers=192.168.4.1 static domain_name_servers=188.8.131.52
interface=wlan0 domain-needed bogus-priv dhcp-range=192.168.4.2,192.168.4.20,24h
interface=wlan0 driver=nl80211 ssid=SSID hw_mode=g channel=7 wmm_enabled=0 macaddr_acl=0 auth_algs=1 ignore_broadcast_ssid=0 wpa=2 wpa_passphrase=PW wpa_key_mgmt=WPA-PSK wpa_pairwise=TKIP rsn_pairwise=CCMP
But after all nothing happens, i tried rebooting and restarting the services but nothing.. There is no SSID
Then I again started with a fresh stretch installation and did every single step like its written in the documentation, but again i had no success.
Can somebody tell me what I am doing wrong? Or how to debug? Or is there even a more simple solution for my problem?
