SIM7000 HTTPS works at "AT Command Tester" but not in "Arduino" #165

Open JGLJGL opened 4 years ago

JGLJGL commented 4 years ago

I made to do both GET and POST in HTTPS, with the programm "AT Command Tester".

But not being able to achieve them if trying to send the comands manually for example with "RealTerm" or with a bridge sketch in "Arduino". I get this responsens por GET and POST int HTTPS: +SHREQ: "POST",400,800 +SHREQ: "GET",400,800

Any idea why it works in one application and not in others?

Here I add the commands I send in case it is helpfull (POST case):

`AT+SHDISC AT+CGREG?

AT+SAPBR=3,1,"APN","ep.inetd.gdsp"

AT+SAPBR=1,1 AT+CNACT=1,"ep.inetd.gdsp"

AT+SAPBR=2,1 AT+CNACT?

AT+CFSTERM AT+CFSINIT AT+CSSLCFG="convert",2,"rapidssl.cer" AT+SHSSL=1,"rapidssl.cer"

AT+SHCONF="URL","https://www.atesens.com" AT+SHCONF="BODYLEN",1024 AT+SHCONF="HEADERLEN",350 AT+SHCONF="IPVER",0 AT+SHCONF="TIMEOUT",30

AT+SHCONN

AT+SHAHEAD="Host:","www.atesens.com" AT+SHAHEAD="Accept:","/" AT+SHAHEAD="Content-Type:","application/json" AT+SHAHEAD="User-Agent:","Opera"

AT+SHBOD="{'PM1':4.0}",11

AT+SHREQ="/api/v1/4444/telemetry",3

AT+SHDISC`

Perhaps it's a line ending issue? So you're saying those commands above work perfectly in AT Command Tester but not in RealTerm?

JGLJGL commented 4 years ago

Yes, that happened. Finally made it work. Headders problem, I commented "Host" and "Content-Type" and added "Connection:close" and it started t work perfectly.

Has anyone really managed to make https work or is it just a myth? :)

davegravy commented 3 years ago

@Bal-Ben I got it to work for a GET request to https://httpbin.org/anything.

HTTPS and MQTTS to AWS IoT is not working for me however.

I receive no response for HTTP Get request for the http://httpbin.org/get URL. Following is the output using the AT Command Tester from https://m2msupport.net

Is there any update on this?

@davegravy have to managed to make MQTTS work?.

Hi, I've managed to get MQTT work. Follow @davegravy flow here However, what was important for me was that the module starts with time 1980-Jan-01, so AWS rejects the connection. I had to do time update manually (AT+CCLK) to test, but eventually setting up NTP for automatic time sync works: AT+CNTP="pool.ntp.org",-16,0,0 (this is for EST time zone).

Once time was correct - AT+SMCONN returned OK and I could do subscribing and publishing with no problems.
