Should I try a different ‘enhance’ firmware or is it a URL problem? When I try to intentionally put a bad URL I get a different error – 603 (DNS Error), which is correct.Ĭan HTTPS work on my phone bowser but not on the sim900 module, or is there a step I’m missing? Please advise. If the problem is network related why are http requests working? Also when I put the sim card in my phone I can browse https sites. Others say after putting a bit more credit/data on sim card it works. From what I’ve been hearing after searching online for a solution is that this could be a redirect. Now while trying to connect using HTTPS I get the above error (Network error according to command manual).Īll HTTP requests are successful though when I disable HTTPS. There was no HTTPS support so I flashed my module with SIMCOM_SIM900 Revision:1137B06SIM900M64_ST_ENHANCE firmware with help from your site.

Hi Sir, I need help with +HTTPACTION:0,601,0 problem My Seedstudio Sim900 board came originally with 1137B13SIM900M64_ST firmware. Operation Research By P.k.gupta And D.s.hira Free. It can detect all DTMF code except +DTMF:4 and +DTMF:5!!! I also use AT+SIDET=0,0 to increase the chance but it didn’t work. When i enable the the DTMF detection by using AT+DDET=1 the module didn’t detect DTMF code 4,5 in case of with old version it worked correctly!!! Its very strange. The problem solved and the module didn’t reset but i found new problem.

I upgraded the firmware to 1137B06SIM900M64_ST_ENHANCE version. Hi dear brother I’m using SIM900 for 4years in a math product(over 5000module) with firmware version: 1137B08SIM900M64_ST_DTMF_JD_MMS but i founded new problem: the module reset when it received an unsolicited code(+CMT.)!!! At fisrt i tried to discard it by using AT+CNMI=1,0,0,0,0 command but the problem didn’t solved. It can be used to decode NMEA data and measure Time To First Fix etc. This archive contains the SIMCom GPS test tool V1.05.
