Quantenna, call_qcsapi call failed: RPC: Timed out

Installing and Using OpenWrt
1

Hello,

I have a Sercomm H500-s router. I followed the instructions for making the 5 GHz wifi SoC work, based on Quantenna QT3740BC:

1 Configure a virtual IP to let the Quantenna SoC communicate with the main SoC. I.e with uci commands.

I think that is done. I can see “lan2” as a network interface and ping it. However I think there is a mistake because the command:

/etc/init.d/network/restart

does not work, it should be:

/etc/init.d/network restart

2 Configure a TFTP server inside OpenWrt, the Quantenna images will be served in the /etc/wlan directory.

I think this works too:

/etc/init.d/dnsmasq status
running

3 Install the qcsapi client.

There is a minor mistake here as the commando with the right package name is

opkg install call_qcsapi_1.0.1-1_mips_mips32-openwrt_21.02.ipk

The package was installed but not properly configured:

Configuring call_qcsapi.
call failed: RPC: Timed out
RPC: Timed out

Any help would be appreciated.

regards

An update: I saw two interfaces with the same IP, “lan2” and “qtn”, both with 1.1.1.1. Then I entered again the instructions from the web but now as “uci set network.lan2.ipaddr=1.1.1.2” When I try to configure the package call_qcsap the error message is not “RPC: Timed out” but “1.1.1.2: RPC: Remote system error - Connection refused” instead. I think that is a hint but I don’t know why the connection is refused. The firewall seems disabled for this interface. The install is clean, with almost no configuration from my side.

thanks in advance

Hello,

I bring this thread up and kindly ask for any hint. My guess is the instructions from the web by @DimmaDont are not totally right. I followed them to the end and find this error message:

root@OpenWrt:~# opkg install call_qcsapi_1.0.1-1_mips_mips32-openwrt_21.02.ipk
Installing call_qcsapi (1.0.1-1) to root...
Configuring call_qcsapi.
1.1.1.2: RPC: Remote system error - Operation timed out

As I pointed above, I am not sure the interfaces are properly configured, as seen in the Lucy web, but this is a system with minimal configuration, after installing from the image:

lucy_lan2_qtn
lucy_lan2_qtn401×338 31.7 KB

Is it that lan2 and qtn must have different IP addresses? If I set lan2 with 1.1.1.2 then the message is:

1.1.1.2: RPC: Remote system error - Connection refused

Or some firewall problem? This router’s 2.4 GHz wifi interface is not supported in OpenWRT so the only choice for making wlan work is this 5 GHz SoC.

Thanks for your help.

Not me, sorry.

Hello

I had made a posible mistake when I upgraded the packages after a clean install. Now I know that is discouraged and unnecessary. I have uploaded the Sysupgrade image and followed the instructions in the device page again. A different error message appears:

opkg install call_qcsapi_1.0.1-1_mips_mips32-openwrt_21.02.ipk
Installing call_qcsapi (1.0.1-1) to root...
Configuring call_qcsapi.
1.1.1.2: RPC: Program not registered

I am running OpenWrt 24.10.2 r28739-d9340319c6 / LuCI openwrt-24.10 branch 25.168.50434~d6b13f6 on a Sercomm H500-s vfes.

Thanks for you help
