Hello
I have installed the 3/4G/LTE base hat on a raspberry with a very long header
My object is to add over the base hat this LoRaWANN gayteway
I can make it working on a Raspverry Pi3 as I can make working the Base Hat.
But I wonder if I add both on the same raspberry, the base Hat and the gateway will works together by installing the corresponding dsoftware
Any experience to share?
Many thank
Hello,
We have not tested it.
Since there is no conflicting pin between the Base HAT and the LoRa HAT, you may use it.
It seams to be working. I just wrote an article here (in french, sorry. I will look to translate it later).
Until now, my LoRaWAN gateway is connected to TTN.
Great,
Thank you for sharing
Dear Saeed,
In fact, it’s look like it’s not completely finished 
.
Yestreday, TTN console showed me a green light regarding the connection, but it may be possible that the green ligth remind green some time even if the connection is lost. This morning my gateway was not connected anymore to TTN even if
ifconfig wwan0
show me a successfull connection

(I changed the IP)
For me, all installation went fine. Before adding the Bas HAT, my gateway could be connected while it was connected to my home WiFi. Now I disconnected from my Home WiFi, as I added the Bas HAT and even if ifconfig showed me a 4G connection, my gateway can not be connected.
I wonder if I missed a step. I thougt the step I did, was enough to connect my Gateway to the network becaue of Base HAT, which return me a successfully 4G connection.
Data could be sent from my Base HAT, isn’t?
However, I wonder if I should install RaspAP and create an Hotspot name “newhotspot”, and then modify the /etc/wpa_supplicant/wpa_supplicant.conf and configure the Wireless to access the hotspot provided by himself.
network={
ssid="newhotspot"
psk="password"
}
Do you understand what I am saying ?
It a bit funny, because usually we connect a devise to a WiFI routeur, but in that case we connect it to himself
NB: from my Raspberry, I can ping
ping www.google.ch
So the connection is good
What’s your point of view?
I did some other test. It looke like the IoT LoRa Gateway send the data only from WLAN. When I clear the WLAN configuration, the data can not be sent to WWAN, even if I can ping a external web site from WWAN.
Is there a way to forward all package from WLAN to WANN?
I run route -n and here is the result
route -n

Any idea why there is this line with an IP starting with 169.254
169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 wwan0
Additionnaly
ip route

192.168.1.0/24 dev eth0 proto dhcp scope link src 192.168.1.107 metric 202
Why wwan show me 169.254.0.0
why when I run ifconfig wwan0, inet show me
inet 10.164.xx.xx netmask 255.255.255.240 broadcast 10.164.xx.x07
It’s look like my gateway does not want to communicate with wwan0
