How do I upgrade a eS-WiFi modules firmware?

Today, we recommend that you use a JTAG connector. We are currently working on two additional methods, use of the boot loader running inside the eS-WiFi or over the air. Over the air updates will require the use of an external SPI flash device to store the new image.

How am I informed of firmware updates to the eS-WiFi module?

All customers that register the eS-WIFI evaluation kits are automatically put on distribution for all firmware releases relative to the product purchased. If you would like additional people added to the update, simply register the user in the “contact us” section of our web site.

Do you need a SLA to purchase the eS-WiFi modules?

Yes, we have a royalty free object code SLA agreement.
