ntp address 132.163.97.3
got ntp response: 19/09/2023 16:05:11
16:05:11 GMT
Rest Call =
GET /maps/api/timezone/json?location=34.2073%2C-84.1402&timstamp=1695139511&key=<my google API key>

*** PANIC ***

Out of memory
Port: COM13 removed

Disconnected

I'm making an API call similar to the OPENWEATHER call, except this is the first time I've been forced to use TLS.

Apparently, I've done it wrong.

Is anyone else calling this GOOGLE API? Hints?

Those APIs can be very sensitive little souls. You have to be very careful what you call them or they can get very sulky indeed, and some will panic if called abruptly!

OTOH I've been known to call Google all sorts of things...

I suspect it depends which thing is creating the PANIC & Out of memory messages.

If it's the Pico it may be that it's receiving something it can't handle - too long or complex or some such.

Well, the response when I do it using a "tool" (advanced Rest Client) shows this is the response:

{
"dstOffset": 3600,
"rawOffset": -18000,
"status": "OK",
"timeZoneId": "America/New_York",
"timeZoneName": "Eastern Daylight Time"
}

... but other than changing the code to use TLS instead of TCP, it's nearly identical to openweather API example.

Basically, I have the URL defined as

dim URL$ = "https://maps.googleapis.com"

The Request as :

DIM REQUEST$ = "GET /maps/api/timezone/json"

And then I append the particulars... like location(lat Lon), Timestamp and my API key into a string called RESTCALL$.

WEB open TLS client URL$,443
WEB TLS CLIENT REQUEST RESTCALL$,buff%(),10000
WEB CLOSE TLS CLIENT

Apparently, the PANIC is from this line of code:

WEB open TLS client URL$,443

In fact, all I need to do to create the *** PANIC *** is a program that looks like this (and nothing else):

WEB open tls client "https://maps.googleapis.com",443

WEB close tls client

There are only a limited number of encryption algorithms supported by lwip. Sounds like you have found one that isn't supported. Also many TLS sites use SSL over TLS and this isn't supported at all

Bummer, It looked like a handy API... and my first attempt at TLS...

Will try http://worldtimeapi.org/ instead, which is what already I *was* using...

Never tried API and TLS before but isn’t this missing the HTTP1.1 piece of the header on the end and all the /r/n's to separate the headers?
