Hi, we are currently working on a product based the famous SparkCore. To contact the Spark inside the WireLess LAN of our customers, they need to know the IP Adress within the Network (to get in direct contact). Is it possible to set the DNS Name with Software? Is there a reason for not using any…

@softmeter , You can use WiFi.LocalIP() to retrieve the IP address of the core. See: http://docs.spark.io/firmware/#wifi-localip You can either Spark.publish() or print to Serial and capture the Local IP address. DNS is used internally by the cc3000 for lookup. I’m not sure what you meant be usin…

If you just want to call your Spark “Brad”, you can put an entry in your PCs hosts file to make that association. If you want a more automatic or dynamic solution, you can try mDNS aka Bonjour but you should know: It is a cooperative broadcast protocol so the core has to keep a continuous connecti…

Normaly in DHCP during a DHCP-Discover Package you specify a Host Name, so the DHCP registers your HostName and your MAC using this name for DNS. Currently this HostName seems to be empty (which is allowed by the protocoll), so the DHCP registers no hostname (therefor you need the IP Adresse to rea…

[image] bko: If you want a more automatic or dynamic solution, you can try mDNS aka Bonjour but you should know: Yup, but this is only needed, if your network does not have an DNS Server. Today, any router or access point is a DNS Server providing DHCP and DNS capabilities.

[UPDATE] I’ve found the answer inside a TI forum. It’s simply not implemented in the cc3000 http://e2e.ti.com/support/wireless_connectivity/f/851/p/206099/739673 :confused: Here is a good Explanation for DHCP and DNS (from Arduino perspective) http://notebook.kulchenko.com/embedded/dhcp-and-dn…

Hi @softmeter DHCP happens entirely inside the the TI CC3000 so we don’t have much control over that. mDNS aka Bonjour is very useful to discover devices on a network even with DNS. That is how you can find your printer or your scanner or your NAS via its attributes. It is particularly valuable …

[image] bko: You might think it could be a perfect fit for Spark but it consumes a lot of resources on such a small host. Yes, this is not an option at all. Maybe the Photon will implement DHCP with Hostname Thx

[image] bko: The protocol is designed to run on smaller processors like printers but it is cooperative and the hosts need to listen all the time for updates. You might think it could be a perfect fit for Spark but it consumes a lot of resources on such a small host. In another forum i've fou…

Hi @softmeter I think you must have missed the link that @peekay123 provided above to a mDNS client for Spark. It works fine but sometime consumes more resources than I would like.
