I agree with you that in step #1 for the PC side that it is written https://www.espruino.com/ide/
and that the 'Relay Key' edit field is not present there.
Espruino is a JavaScript interpreter for low-power Microcontrollers. This site is both a support community for Espruino and a place to share what you are working on.
@user80065,
I agree with you that in step #1 for the PC side that it is written
https://www.espruino.com/ide/
and that the 'Relay Key' edit field is not present there.
Maybe @Frida is trying to imply that https://www.espruino.com/ide/relay/ is used on both ends perhaps, and that step #1 has 'improved' since five months ago?
Such that the relay link-app is used to pair the two, then use https://www.espruino.com/ide/ to access perhaps?
The input field is under Settings >> Communications>>Relay Key:: (Last Entry)
as Frida indicates.
My outbound BLE device can't connect, so I am unable to test this idea on PC side.
