I do not know exactly how many concurrent connections the RPi 3 can handle, but a typical number is 8 connection. The limitation is most likely in the BLE HW, not in the software. RPi 3 have a BCM43438 combined WiFi/Bluetooth chip, you might find some details in the datasheet, or by asking on a Raspberry forum.

I'm able to ping it YAAAAAY !!! also I wanted to know how many nrf52 nodes can be handled by my raspberry pi 3 border router at a time.

That is good to hear! Yes, as the message say, it is already mounted and does not need to be mounted again. You can ignore this command if it is already mounted.

Yes, I'm able to connect my nrf52832 with raspberry pi 3. I just wanted to clarify one thing. When I enter the command "mount -t debugfs none /sys/kernel/debug" this shows up :

is this ok ? because I enter the rest of the commands and no error shows up.

No worries! Did you get it working now?

There is a typo on line 6 of your radvd.conf file. Please change AdcOnLink to AdvOnLink.

Here is the screenshot for the command "systemctl status radvd.service"

And here's for the other command. I'm new to raspberry pi so I have no idea what these errors mean . Hope you can help me .

Thanks a lot for helping me

Yes, it looks like you will have to create the file manually. Could you provide the output of the "See ... for details"-commands mentioned in the bottom of your screenshot?

Yes I did radvd. The tutorial says that "The RADVD configuration file is located in /etc/radvd.conf"

but there was no radvd.conf file. I created a new one and used the default prefix given in the tutorial (2001:db8::/64 )

Most examples run "sudo su" first to login as root user. Did you install radvd?

Hey,

Okay so I already have precompiled bluetooth_6lowpan in my kernel as I'm using rasbian stretch 4.9 but now I get an error when I run "sudo service radvd restart" in this step . I had to modified the

"sudo echo 1 > /proc/sys/net/ipv6/conf/all/forwarding"

part because apparently sudo doesn't work there is redirection (">") involved. I'll attach the screenshot for better understanding

Yes, the documentation looks outdated. Please have a look at this answer. You should not need to recompile anything when using Rasbian Stretch (Kernel version: 4.9).

Hey,

I have followed the tutorial given in SDK14.2.0 link . But it's the same procedure and I still get the error. But then this is for installing the kernel and you say bluetooth_6lowpan comes precompiled so how can I check it (I just want to be sure)?

Hi,

The documentation you are linking to is outdated. In later versions of Ubuntu, Raspbian, etc., the bluetooth_6lowpan module comes precompiled in the kernel, no need to compile the kernel manually to add this. I would recommend that you take a look at the documentation for SDK 14.2.0, which include the latest IoT libraries. There is also a user guide for setting up BLE 6LoWPAN Border Router.

Best regards,
Jørgen
