BLE and other measurements with OpenWRT

[snow_mm]

Hallo,

many years ago I have used OpenWRT simply as a router. It will have developed a lot so I am kind of new again, please be patient

Would OpenWRT support BLE connections ?
Is it possible to collect informations like wifi/BLE from other antennas strength ?
if so seperatly for each antenna ?
Also would allow OpenWRT to run some code (prefereably python) to collect weather infos from sensors ?
Is there some monitoring connection (mqtt/ grafana....) ?

I was thinking about Spitz GL-X750 dual-band router as a remote weather station /pax counter

Thanks for any hint here

You cannot use the WiFi radio to monitor non-WiFi signals. WiFi devices are not general-purpose SDRs (software defined radios). Additionally, most WiFi devices do not have a BLE module built-in.

@snow_mm

Would OpenWRT support BLE connections ?

Does your device support BLE (or have you purchased such a module)?

See:

IPv6 over Bluetooth Smart (Low Energy)

@snow_mm

Is it possible to collect informations like wifi/BLE from other antennas strength ?
if so seperatly for each antenna ?

• As discussed above, WiFi only, BLE would require a separate device
• Not separately, for the whole radio

@snow_mm

Also would allow OpenWRT to run some code (prefereably python) to collect weather infos from sensors ?

What protocol will be used to establish a connection with these sensors?

Thanks @lleachii , maybe I did not clarifiy what has to be done

for wifi I would like to see from time to time which other wifi devices are switched on.
Usually on the console with airmon-ng or kismet. I that possible with OpenWRT ?

for BLE kind of the same, don't have a solution yet.

For the sensors I would connect some usb device and recieve serial output from them.

All this should than be forwarded. Is it possible to run such a custome code stuff in OpenWRT ?

[lleachii]

• Yes, it is possible to run airmon-ng, it is an available package in the repository
• Yes, it is possible to run custom code on OpenWrt - you mentioned Python, that is also an available package

@snow_mm

for wifi I would like to see from time to time which other wifi devices are switched on.

You can see this for your own devices connecting to your AP by default.

@snow_mm

Is there some monitoring connection (mqtt/ grafana....) ?

Feel free to search the forums, there are a few threads.

USB serial is supported.

Thanks for that, sounds promising !
