I understand this issue is closed but leaving this here in case it helps someone else:
The issue for me was that the batctl installed using sudo apt-get install batctl is too old and therefore was resolved by updating the package:
- Remove the package -
sudo apt-get remove batctl - Clone the repo with up to date version -
git clone https://git.open-mesh.org/batctl.git - Change directory -
cd batctl - Compile package -
sudo make install - Reboot -
sudo reboot

I've done some testing and it looks like the issue is with batctl instead, there's a massive version desync with batman-adv module (v2020.4) and batctl present in the raspberry pi repository (v2019.0) and with the latest update of the raspberry pi kernel (from 5.4 to 5.10) this gap has broken batman-adv.
This can be fixed with the following which updates batctl:
sudo apt purge batctl -y && \
sudo apt install libnl-genl-3-dev libnl-3-dev -y && \
wget https://downloads.open-mesh.org/batman/releases/batman-adv-2020.4/batctl-2020.4.tar.gz && \
tar -xvf batctl-2020.4.tar.gz && \
cd batctl-2020.4 && \
make -j 4 && \
sudo make installMight be worth writing to the raspberry pi people and asking them to update the package instead of having to change the batctl version every kernel update
Also, had an issue with pinging/ connecting to nodes, fixed it by changing the MTU value of bat0 to 1400 and leaving wlan0 as 1500

Same problem on Raspberry Pi Zero W (Buster 10.8 up-to-date).
Note that "/sys/class/net/wlan0/batman_adv" is missing.

Im not fully sure yet, but I think this is due to that batman-adv and batctl are very old in default packages from Raspberry OS.
I have downloaded latest batman-adv from https://www.open-mesh.org/ and compiled it.
Then I do not get "wlan0: error reading status" and "Error - interface bat0 is not present or not a batman-adv interface."
Have some things left to test but looks promising with new versions.

I updated only batctl as you described. Now I see the other device as neighbour but not as originator.
MTU is 1400 but ping is not working.
Any hint?

I have 2 Raspberry Pi Zero W: batman1 (the gateway) with an external usb wifi for connect to the standard router and batman2.
I use onboard wlan0 for batman.

Try using the standard ping instead of the batctl one.

Something is wrong with the startup scripts if it's unreachable, they aren't connecting 2 each other.

I tried with "batctl tcpdump bat0" bat I can't see any packet coming from the other host.
If they are visible each other other as neighbours, the wifi config should be ok, isn't it?
I used this configuration:
iface wlan0 inet manual
wireless-channel 5
wireless-essid srmesh
wireless-mode ad-hoc
Another doubt: no originators are visible... is this correct?

There should be sudo at the beginning of most of the commands in the scripts. Also, the IP address on the standard/ non-gateway node shouldn't have its IP set by ifconfig, it should be given an address by the gateway's DHCP server.

There's no sudo because I used root user directly. If I don't assign ip on client host I get a 169.254.x.x address (surely because they don't talk each other).
I can't figure out where the problem could be in the full stack.
When I have more time I will test the same configuration on Raspberry PI 3 using ethernet to detect if the problem is on batman or on wifi.
