Unable to connect to device with pc-ble-driver-py 0.16.3

I resolved my issue. I was apparently programming the connectivity hex file incorrectly. Before, I was flashing the device through:

nrfjprog --snr <mac-id> --program <connectivity-hex-file> --chiperase --family NRF52

I ended up getting it to work by flashing the device through the nRF Connect For Desktop UI. Not sure why this is the case, but good enough for me 😛

I've also tried this with both 32-bit and 64-bit Python versions without success. This run was testing with pc-ble-driver-py 0.14.2 as I wanted to check if a previous version would work, but you can see this fails as well.

[quote user="LimeSlice"]Hi, yes serial_port_enum.py works fine. I get that COM4 is the only COM port available for the NRF which is correct.[/quote]

Can you post the output from that? Did you get "Port "{}" already flashed with connectivity firmware" ? or "Flashing Port"-> "Firmware flashed" ?

Does heart_rate_collector.py work after you run serial_port_enum.py ?

Hi,

[quote user=""](No response from device. Tried to send packet 6 times.)[/quote]

Are you sure that you are using the correct COM port? Does running the serial_port_enum.py example work?
