Yes. SMS is working. I am getting a 603 Error code.
603 is access denied I think. chack your API key. Make sure you can update the channel via browser.
Can post via browser. Have you all changed anything highlighted in bold below?
I am now getting a 606 code.
It is all pointing to changes on your side to levels not supported by the below.
I have been using SSL to connect a SIMCOM SIM800 GSM Module to a Microsoft Azure function endpoint. This has been working for months and has now stopped working and reports a 606 error code which indicates an "SSL alert message with a level of fatal result and the immediate termination of the connection" according to SIM800 Series_SSL_Application Note_V1.02
I tried HTTPS connections to various other sites using the SIM800 e.g. google and httpbin and got mixed results: I could connect to some e.g. google but not others e.g. httpbin. See here for a similar result.
Does anyone know if sites have recently changed SSL cipher or protocol requirements? The SIM800 module (only) supports SSL2.0, SSL3.0 and TLS1.0.
My channels and devices are all behaving as expected. Do you have any communication with your device? Can you see if it is connecting to the wifi? Fluctuations in wifi are the most common cause of loss of data. What kind of device is it?
Mine was working last year. Powered up my system this year and it no longer send information. I have not changed anything.
