Not able to see gateway on nrF Connect (bluetooth)

[pradeeptewary]

I am able to compile and boot gateway_config, but it is NOT showing in helium or nrF app during bluetooth scan. I have attached the console, error and crash logs (and erl_crash.dump file) for the reference. console.log crash.log error.log erl_crash.txt

Following are the logs of the gateway while running;

$ sudo ./rebar3 shell

While running in other mode, described on repo, following output is given my app:

Also, while running the following dbus-send command, we get the following errror: $ dbus-send --system --print-reply --dest=com.helium.Miner / com.helium.Miner.P2PStatus Error org.freedesktop.DBus.Error.ServiceUnknown: The name com.helium.Miner was not provided by any .service files

Please help?

Looks like you maybe missed a step in https://github.com/helium/gateway-config#install where you need to copy a dbus config file to the right location and restart/reload dbus to have it pick it up.

The no_access is also a likely indicator that the user you are running gateway-config as does not have permissions to access the dbus socket. Make sure the user is in the bluetooth group (or whatever the right group is on your distro)

1. Dear @Marc I had followed the steps of the repo and the conf file exists in the said location (can be seen from the following ls) pi@raspberrypi:/etc/dbus-1/system.d $ ls _avahi-dbus.conf com.helium.Config.conf com.redhat.NewPrinterNotification.conf dundee.conf org.freedesktop.DisplayManager.conf org.opensuse.CupsPkHelper.Mechanism.conf wpasupplicant.conf bluetooth.conf com.hp.hplip.conf com.redhat.PrinterDriversInstaller.conf ofono.conf org.freedesktop.PackageKit.conf pulseaudio-system.conf

2. Also for the no_access error, i couldn't understand completely but I can see the bluetooth group in the groups list. pi@raspberrypi:/etc/dbus-1/system.d $ grep root /etc/group root:x:0: bluetooth:x:112:root,pi lpadmin:x:117:root,pi

$ groups pi adm dialout cdrom sudo audio video plugdev games users input render netdev bluetooth lpadmin docker gpio i2c spi

Also while running the following command from the build release, I get the following error. $ bin/gateway_config advertise on

Node 'gateway config@127.0.0.1' not responding to pings.

Please help?

[pradeeptewary]

I tried $ rebar3 release and while executing _$ bin/gatewayconfig start or foreground, it doesn't show any error and we are able to see the ping response (pong) and pid. However, It is not visible in helium app. When I run the _$ gateway_config:advertiseenable(true) from the erl console, the pi shows in the helium app. And while pairing the pi, I get the Error, characteristics (UUID_GATEWAY_GATT_SERVICE and UUID_GATEWAY_GATT_CHAR_WIFI_SSID) read failed for device. Also, when i check the console logs, i see following warnings and errors:

Good, so you figured out (as the readme says) that you need to have gateway_config running to be able to use it.

• Gateway-config will enable advertising only when told to do so. Most makers that use the BLE feature and don't have a button use the advertising on cli on boot up of their firmware to turn on advertising for a minute to allow the user to connect
• It looks like there was some error in gateway_config that I can't quite figure out.. Do you have a crash report from crash.log with the {undef,[{grpc_lib,keytake error in it? It almost looks ike you only have a partial build
• NOTE that gateway-config master will not work with an erlang miner anymore, but only works with a running gateway-rs
