Serial issues?
Posted: 19 Mar 2019, 03:35
I'm honestly not sure if this is a problem or expected behavoir, but as it's something I noticed, I figured I'd ask.
I have an RFLink kit from Nodo shop built, along with the wifi adapter and a NodeMCU. When I remove the wifi board and connect a terminal program via USB to the mega, everything works fine. I get messages when I trigger a sensor, and I can issue commands such as 10;PING; or 10;VERSION;
Things change when I connect the wifi board. I have the NodeMCU flashed with the esp-link firmware (https://github.com/jeelabs/esp-link) and it appears to work for receive - with it running, connecting to the esp-link web interface I can see the data from the RFLink. However, with the board connect, it seems that I cannot *send* commands like 10;PING; to the RFLink, either through the web console or through the still-attached USB cable. Both see the data RFLink sends, but neither seems able to send commands.
Anyone have any ideas on what's going on here? Is this an indication of a problem or expected behavior?
Thanks.
