I am writing a provisioning automation (with robotframework), but I am stuck at writing the signed device certificate back to the device.
When writing the certificate:
at AT%CMNG=0,16842753,1,"-----BEGIN CERTIFICATE-----\nMIIBNjCB3QIUa8FPDeUucXyBAAzh4DtcbGXEhrUwCgYIKoZIzj0EAwIwDTELMAkG\nA1UEBhMCREUwHhcNMjUwMjE4MTYzOTA0WhcNMzUwMjE2MTYzOTA0WjAvMS0wKwYD\nVQQDDCQ1MDMzMzY0Ny0zMDM0LTQ5ZGUtODBjYy0wYTA5ZWUyMjBkZDAwWTATBgcq\nhkjOPQIBBggqhkjOPQMBBwNCAAQ4V/Rqw4/K7PO2aAZ1O0T81EcthEIUmuw5cXAC\n+zdzYJwl9umhhnT8v42ffEBhPLF4UomQHjmFq1DWjZviOep6MAoGCCqGSM49BAMC\nA0gAMEUCIQDNI6csY6NxNDA7S7gSaU+LrCZhQtyfQo9aPeKV/HbkfQIgdgT1lG6j\nyjOZnXY5GAFwacj/6Z6VWdBRlhTR3n9JY08=\n-----END CERTIFICATE-----\n" ERROR
So I tried to follow the solution proposed by Nordic.
I flashed the modem-shell:
west build -b plank/nrf9161/ns -p auto samples/cellular/modem_shell && west flash
and ran the scripts in github.com/.../utils.git:
python create_ca_cert.py -c DE
and
python3 device_credentials_installer.py -d --ca 0x2e5fe5690e73f597194ab754cf53ff394840ada4_ca.pem --ca_key 0x2e5fe5690e73f597194ab754cf53ff394840ada4_prv.pem --verify --delete --cmd_type=at_shell
But I get the same error again, please find the log attached:
python3 device_credentials_installer.py -d --ca 0x2e5fe5690e73f597194ab754cf53ff394840ada4_ca.pem --ca_key 0x2e5fe5690e73f597194ab754cf53ff394840ada4_prv.pem --verify --delete --cmd_type=at_shell
