received my 2 Spark cores today, thanks. Very professionally made, looking great, website instructions also very clear. Great stuff.
Spent hours trying to make it work but I was always stuck with flashing green LED (ie can’t connect to WiFi). I was experimenting with various settings, but nailed it down to a following, when it finally stopped flashing green and started working properly:
SparkCore only supports:
- 2.4GHz WiFi (no 5GHz support)
- 802.11b/g network only with 20MHz channel bandwidth (ie no N or AC)
- Channel numbers up to 10 (why?!)
Thankfully I have a router (ASUS RT-AC66U) that could independently configure various separate SSIDs, so I don’t have to downgrade the whole home WiFi system just to make SparkCore work. But there might be users, that don’t have the access to settings or a knowledge how to change them. The only working SparkCore WiFi config is Legacy b/g 2.4GHz manual low channel number, which is frankly very basic and might cause problems to quite a few users working in much more modern environment.
Please include this limitation in your specifications and update the WiFi Setup and Troubleshooting sections. It will save hassle to a lot of people.
Many thanks and keep up the great work.
