I am trying to send data to thingspeak.com.
I am using mbedTLS for https, but in the handshake steps client hello is not working it returns following logs,

I am able to use HTTP get and send data, but the problem comes in the handshake when I use mbedTLS.
whether I can send raw hex values using CIPSEND? or I had to use any other characters?
