When I was running the heart rate example, I would report this error below, someone tell me what caused this error, which causes the driver to fail to recognize now. But I found the device on the NRF connect desktop and on the command line.

python3 heart_rate_collector.py NRF52 /dev/tty.usbmodemC8A5C57A42372 ['heart_rate_collector.py', 'NRF52', '/dev/tty.usbmodemC8A5C57A42372'] Serial port used: /dev/tty.usbmodemC8A5C57A42372 2020-05-07 16:40:30,680 [123145336700928/LogThread] Successfully opened /dev/tty.usbmodemC8A5C57A42372.

Hi, it looks like you are using an incompatible connectivity firmware on the device. You'll need a connectivity that uses SoftDevice 5. If you have programmed the device with BLE app in nRF Connect for Desktop you will have SoftDevice 3, which would explain the error message. Correct connectivity hex files are in pc_ble_driver_py/hex folder.

我测试一下。
