Hello!
I use blynk with bluetooth connection and my own hardware library.
Now i don’t understand which string i have to use when i want to send push notification or email.
i mean string like [20 1 8 “vw” 0 3 0 123] - write 123 in the v pin № 1.
I didn’t find the answer in the github library.
Blynk doesn’t use any virtual pins.
Your title mentions emails, your post mentions Bluetooth and a custom library and then you say Blynk doesn’t use Virtual pins… Your entire topic does not make sense.
Might sorta work… I haven’t tested how the brackets will affect it, but definitely need to change the quotes to something else like apostrophes as I have done.
