I notice my Wio Terminal cannot associate or scan past Channel 140 on the 5GHz freq. Is this a Limitation of the Wio Terminal? I live in the USA, and I would like to be able to use the U-NII-3 channels 149 - 165 but haven’t been able to get it to work.
What am I missing?
We are aware of the problem and are working to fix it.
That is great!
Thanks!
I banged my head on this one for quite a while, was glad to find this thread and solve the problem (temporarily) by changing my 5GHz WiFi channel.
How will resolution of the 5 GHz upper channel problem be announced to WIO Terminal users?
Thank you,
Robert
https://github.com/Seeed-Studio/seeed-ambd-firmware/tree/dev-WiFi @rentwist We’re working on it, so check out GitHub.This problem is resolved when dev-wifi is merged into the master.
Thank you for the reply and efforts Baozhu!
Hi Baozhu,
I got notice of the update and have tried it out. Unless I have done something wrong, I now see NO WiFi signals at all! Is this expected with the update? I did read something in the read.me which said Bluetooth only but was not sure what this meant. Do you have any insight or advice?
Thank you.
Robert
We also updated the Wiki yesterday. Please follow the wiki.
I believe you left out the need to install the RTOS library in the new rpcWiFi Wiki instructions. Figured this out and got it working though. 5 GHz upper channels (above 140) show now!
Thanks,
Robert
Hi @rentwist
We have moved the FreeRTOS to the ArduinoCore board library for Wio Terminal, please update to the 1.8.1 verison 
I did see that note in the rpc instructions but was confused as to how this is updated (and where to find it in the IDE). I concluded (incorrectly I guess) that it was the Arduino IDE version, which is similar in version number to my current IDE version, I have 1.8.12. Could you give a noob (me) a little push in the right direction?
Thank you!
Robert
Never mind! I figured it out, update board under IDE Boards Manager!
Thank you.
Thank you guys, I was also looking for this information:)
