No. 1492	Re: Change without Reset -EMC -864Mhz pollution	2017-05-12

Dear BOGLYAS Christophe, Thank you for using our products. I answer four questions in order. - The interval parameter does not have any meaning in this case. Its original meaning is desicribed in page 9 of this document: http://www.eztcp.com/documents/application/an_ip_change_notification_en.pdf - To avoid the power reset when changing IP address, you can change IP address via AT command. To AT command, please refer to: + Page 27, 39 to page 42 of User Manual http://www.eztcp.com/documents/manual/csem53nen.pdf + https://www.eztcp.com/documents/application/an_atc_mode_en.pdf - The CSE-M53N'ss interface is silmiar to the CSE-M53 but its core is very different. It is very hard for us to give you an proper solution. But I recommend you to add a bead between 3.3V power line in series. (Let CSE-M53N get its 3.3V power through the bead.) - I am afraid but I don'st have any idea for this issue. I think that some protection component(for example: TVS) would be helpful. I hope the above is useful to you. Please feel free to contact me if you need any further information. Thank you, Best regards, > BOGLYAS Christophe wrote: > ------------------------------------ > Hi, > I have tested your firmware 2.1A (sent to Mr BACHELET item 1481) and it looks fine for Host configuration.
