Hi, I am trying to perform HTTPS (SSL) connection to an online Google Firebase real-time database using the HL7800-M. However, I am not able to connect using TLS 1.2 because I am receiving “+KHTTP_ERROR: 1,5 //HTTP connection error due to internal trouble”. Below is my command sequence. I appreciat…

I realized I made a mistake by connecting using port 80 instead of 443. Below I have attempted to connect with HTTPS to www.howsmyssl.com to check that I can even perform that connection. As shown, I am still receiving the HTTP_ERROR: 1,5 (internal trouble) error. Any assistance would be appreciated…

Hi, Please use the correct certs. You should use 1220 bytes of the certs for AT+KHTTPCFG=1,“ www.howsmyssl.com ”,443,2. Here’s my log: （Test in v3.6.2). at+kcertstore=0,1220,0 C:\Users\klin\DSTRootCAX3.crt OK AT+KCERTSTORE? CONNECT root_cert,0,1220 -----BEGIN CERTIFICATE----- MIIDSjCCAjKgAw…

Thank you so much for your response! How are you writing .crt files to the HL7800? I am using Terminal (mac) and the gnu screen automated with bash to write commands. I went to Lets Encrypt and downloaded the same .pem (.crt) file that you are using but am still not having any success. Writing that …

Hi Mitlight.co , There’s 0x0D 0x0A at each line in the orignial DSTRootCAX3.crt (The size is 1220 bytes). But it seems when you use your terminal, 0x0A is removed, only 0x0D is there(check by Hex mode). That’s why only 1200 bytes your side. Please check the setting of your terminal.

Hi @Sierra_klin2 , Thanks for your comment! That makes perfect sense and I was able to adjust the writing mode (and using minicom) to incorporate the 0x0D 0x0A (). However, I still received the +KHTTP_ERROR: 1,5 after initiating the connection. Attached is my command log. You’ll see that I have the …

Hi @Donald , Thanks so much for your input in this debug. Your example TLS1.2 command guide is excellent and I have re-written my command bash sequence to follow suit. I was able to obtain the CA certificate (root CA) and client certification (intermediate/public key) from my firebase URL using Open…

Hi Stephen, I test with the FW 3.7.2.3 but in NB network. AT_LOG_3.7.2.3.txt (2.3 KB) It works my side only if I use domain name AT+KHTTPCFG=1,“ www.howsmyssl.com ”,443,2,0 instead of IP address AT+KHTTPCFG=1,“35.227.42.200”,443,2,0 Plesae try the same.

Hi @Sierra_klin2 , Thank you so much it’s working! Following that simple change (even though I am using Cat-M1), I was able to get an HTTPS connection (for the first time!). I have attached my command log for others to reference. Hows My SSL Success.txt (11.2 KB) From here, I am now attempting to …

Hi @mitelight.co , If I want to attempt a connection, do I need a private key purchased for my HL7800-M? –> Yes, You need store private key to HL7800-M.
