com port.
Note: The default baud rate on the BL620 is 9600 bps.

PGRADE
The BL620-US is already preloaded with firmware. When new firmware becomes available, customers can upgrade
the firmware over the USB interface. The procedure is quite straightforward. Be aware that all
smart
Basic
applications and settings are cleared after the upgrade.
The firmware package can be downloaded from
https://laird-ews-support.desk.com
, and login credential will be
required. Customers should visit the website to submit the request.

Send at i 8 to ensure the correct com port is opened.

The upgrade package is provided as a zip file so decompress it into a new folder of your choice. The form of
the file name is: BL620_R2_Firmware_&_Samples_smartBASIC_Apps_vW_X_Y_Z-rN where W,X,Y,Z is the
version number of the firmware and –rN is an optional suffix that is present if the zip file has new content
apart from the firmware image (such as corrections in the user guide or other documentation.
Note: Do not decompress into an existing folder, as there is potential for confusion with regards to
firmware upgrade files. We recommend you decompress the zip file into a folder with the same
name as the zip filename.

In the decompressed folder, launch _DownloadFirmware_vA_B_C_D.bat (either double-click it or launch it
from a command prompt console window). Upgrade process will start immediately.
