#67917 Hi all,
I'm trying to enable tls in the mqtt communication.

Below what I'm doing... let me cut the code that I believe is not important.

With MQTTSpy, from a workstation, I can connect to the mqtt broker, using the same certificates and parameters.

With the ESP01, it crashes at the beginning.

What I'm doing wrong? How can I debug the issue?
Do you have suggestions?


At the beginning I load the certificates
Code: Select all#include "certificates.h"

Then I instantiate the pubsubclient client
Code: Select allWiFiClientSecure espClient;
PubSubClient client(espClient);

and finally I try to estabilish the connection
Code: Select all   
espClient.setCertificate(certificates_sensor3_bin_crt, certificates_sensor3_bin_crt_len);
espClient.setPrivateKey(certificates_sensor3_bin_key, certificates_sensor3_bin_key_len);
client.setClient(espClient);
client.setServer(mqtt_server,mqtt_server_port);


This is the certificates.h
Code: Select allunsigned char certificates_sensor3_bin_crt[] = {
  0x30, 0x82, 0x03, 0x7f, 0x30, 0x82, 0x02, 0x67, 0x02, 0x09, 0x00, 0xa9,
