I became inspired from the local communication example. so now I am trying to make a local Restfull api. So i started humbly with creating a webserver that returns the message that had been sent. similarely to the other problems (mentioned below) i run into stability issues. here is my code: TCP…

Hey All! We’re in the process of reviewing fixes and firmware pull requests and merging them in. Right now you can pull the latest master from all the repos and compile locally, but we’ll probably update the stable ‘compile-server2’ branches of the firmware sometime next week. Thanks! David

@Noten @tomas The Web IDE uses a stable version of the firmware to which the user app is added to. When we roll out changes or updates, they are first made to the master branch on the core-firmware repo. In order for anyone to test latest fixes before they show up on the web IDE, they will need to …

@mohit and @Dave thanx a lot for your quick response. I found the instructions for the manual update to be abit outside my technical comfort zone, but after trying it seems like I managed to get it to work. :smile:

@satishgn , your code works perfectly. Thanks a lot for your help as well!

I seem to be running this issue with the current master of all three repos. My test application.cpp is included at the end of this post. After some amount of time the Core seems to crash. It crashes somewhere between Serial.println(" -- Connected -- "); and the Serial.print(c);, but I don’t know exa…

Can someone help a noobie out here? I’m trying to make the TCPServer example work. Can I use puTTY as a client? If so, what is the host name? sorry if this is silly.

Hi @captnkrunch If your router is setup for DHCP like most home routers, you will likely have to use the IP address of the core instead of name. You can find the IP address on the core with the Network.localIP() method, which you could print on serial or have a Spark variable to get etc. or you c…

Hey @captnkrunch , Did you get things sorted with the TcpServer example? Thanks! David

I appreciate the thought and the help. Unfortunately the simple answer is “no.” I can’t get cli nor nodejs to work so I’m buying a serial LCD and will try to discover the IP address that way.

Hi @captnkrunch , I’m not sure if you’ve tried this yet, but one alternative would be to store the IP address for your core in a Spark.variable. I’ve done this a few times with my apps to more easily find my core locally, here’s some code: char myIpString[24]; uint8_t gotIP = 0; void setup() { …
