Can't connect to Obd after first time
Hi, I'm having a strange issue in which the simple example works only the first time I execute the code ,but once I try to execute again , I get the error which seems to be common here , the only way to make it work again is to reboot the whole pi.
"serial.serialutil.SerialException: read failed: device reports readiness to read but returned no data (device disconnected or multiple access on port?"
I've already configured dbus-org.bluez.service with ExecStart=/usr/lib/bluetooth/bluetoothd -C ExecStartPost=/usr/bin/sdptool add SP
and I also tried to clone the library from repository but still ..
the second issue which might relates to first one is that whenever I use the Async Connection , it always returns none.
I'm using Raspberry Pi 4 with Bluetooth OBD
From what you're describing it seems more of a problem with the connection to the adapter than a problem with the OBD library itself. Maybe try to manually open a serial connection to the adapter to see if that works?
What OBD adapter are you using? I saw a problem with fake ELM327 adapters. A second connect would fail. For me unplugging the OBD adapter and plugging it back in solved the problem.
