Program with mbed-http doesn't run on L-Tek FF-LPC546XX

Mbed OS
1

Hi,

I’m using the mbed-http library to make a HTTP POST request with TLS. But when I compile the program (using the online compiler) and run it on L-Tek FF-LPC546XX, nothing happens at all. There’s nothing to see in the serial monitor. If I comment out all the code that is related to the http request (from “printf(”\n----- HTTPS POST request -----\n"" and downwards) the program runs perfectly and connects to the wifi-network.

I’m able to make a http post request (without TLS), with no problems.

I’m using a ESP8266 connected to the board.

Could you help me out? Thanks.
