The speed of the upgrade is susceptible to the connectivity of the network.
•
ERROR will be returned if the upgrade fails due to unfavourable network conditions. Please wait

for some time before retrying.
If using Espressif's AT BIN (/esp-idf/bin/at), AT+CIUPDATE will download a new AT BIN from the
•
Espressif Cloud.
• If using a user-compiled AT BIN, users need to make their own AT+CIUPDATE upgrade. Espressif
provides a demo as a reference for local upgrade (/esp-idf/example/at).
• It is suggested that users call AT+RESTORE to restore the factory default settings after upgrading
the AT firmware.
