Question

Hey all,

I'm trying to run the node cli flash "imei" -f /path/to/firmware.hex command on the terminal. It prompts as ERROR flash <deviceId> failed!,

ERROR Error: No such file or directory, cannot open /dev/ttyACM0

Can anyone help me with this in solving?

Hi, Can you share som more info and elaborate on the goal you have and what you are doing. I dont fully understand how to help right now. Is this what you are trying ? Provisioning using the CLI — nRF Asset Tracker 11589ff09d3c1d2a550056bc01d7469730c860b3 documentation (nordicsemiconductor.github.io) Provisioning the certificate — Bifravst v10.4.8 documentation Do you have the nrf9160 connected to ACM0 or som other port?

Make sure your device is connected to `/dev/ttyACM0`. If you use another port, you can specify it as an argument. 
 See `node cli flash --help` for details.
