Open LairdTurner opened 3 years ago

LairdTurner commented 3 years ago

Hello!

I'm usig a Lilygo TTGO T-Call V1.4 and I'm trying to upload a certificate to the 800L chip. For this I want to use the more/SIM800_SslSetCert.ino example from the example library.

But the ESP-32 comes up with this error

No idea. Are you using the example exactly; if not, can you paste your code? Can you parse the dump?

You could try this alternative. It is based on a wrapper for handling SSL. Works perfectly with my board LilyGo T-Call SIM800 (v1.3). Your version is 1.4, so you may have to change the definition of pins to the corresponding ones.

Yup - I tried the alternative and it worked. tested with my MySQL server and Telegram. Both working fine.

use this library, dont use the one installed in Library Manager. That one is by OpenS Lab, does not work with TinyGSM

@fbi1671 https://github.com/fbi1671 How did you make it work? I am getting an error like "no matching function for call to 'SSLClient::SSLClient(TinyGsmClient*)'". Could you help me out?
