Проблема в тесте L2CAP - Bluez [закрыто] ⇐ Linux

[Anonymous]

В настоящее время я тестирую инструменты Bluez, такие как L2P и L2Test, поэтому я намерен взаимодействовать между двумя устройствами через слой L2CAP. Я клонировал репозиторий Bluez на двух устройствах Raspberry Pi и сделал необходимую конфигурацию для выполнения этих инструментов, но вместо этого я не получил ожидаемый выход, застрявшая на уровне сокета во время стадии подключения на отправителе, из -за которого приемник ожидает на этапе принятия, этот результат на любом хосте находится вниз, или подключенные ошибки, я также попробовал эти образцы инструментов на двух разных системах (PC).$ sudo ./tools/l2test -p C5:86:1A:53:D7:3B

Here, I made a NRF device as peripheral which is discoverable & connectable, it advertises its info, using which it can be connected, this device can be connected using bluetoothctl but couldn't be connected using l2test
Two Raspberry Pis running BlueZ. My goal is to establish an L2CAP channel using tools like l2test and l2ping. The peripheral device (nRF52) successfully advertises and can be connected via bluetoothctl, but any attempt to connect using l2test fails with errors like Host is down or Connection refused. I've also replicated the test between two Raspberry Pi devices with the same result: the server waits on a PSM, but the client fails to connect. I'm trying to understand if this is a configuration issue, a limitation of the tools, or if additional setup (e.g., registering a PSM for LE CoC) is needed. I'd appreciate guidance on what's missing or how to properly use L2CAP over BLE with BlueZ and Zephyr.
2nd Approach using two PI devices
pi@raspberrypi:~/bluez $ sudo ./tools/l2test -V le_public -r
l2test[2278]: Waiting for connection on psm 128 ...

pi@raspberrypiclient:~/bluez $ sudo ./tools/l2test -V le_public -s DC:A6:32:76:10:DA
