Hi @GabrielNotman and thank you very much.
I have tested your code but same problem has happened. Every HTTP command works except AT+HTTPSSL=1. It shows ERROR as answer. AT+HTTPSSL=0 and AT+HTTPSSL? too.
I wrote an email to SimCom support and I have received response this morning. I couldn't write here until now . As I suspected, It is firmware version problem. I attach a functionality/firmware version table that simcom support has send me.
As you can check on image, firmwares end with BT don't support SSL function. My gprsbee response to AT+CGMR with "1308B05SIM800H32_BT" so, obviously, SSL isn't supported.
If I want use SSL functionality, I need to change the firmware version. I have downloaded tools and firmware 1309B11SIM800H32 (the latest) but I can't update it. Upgrade tool never start comunication with SIM800H... it is always "waiting" response from module. I have tried with Mbili Serial1, with UartsBee, but I haven't success for now. I'm becoming crazy because I need SSL functionality to reach our real webserver HTTPS...
@GabrielNotman, do you know where is J3 connector? I can't find J3 on gprsbee board. I have seeing rev6b schematic and I see that J3 has D+,D-,VBUS usb lines. Modules can be upgraded through USB lines instead of Uart lines so I have been thinking on use this lines and try luck to upgrade module.
Maybe, it would be a nice feature to put an USB on gprsbee board to upgrade them or maybe, give us an option to select firmware version when we buy them.
I would be grateful if someone could help me to change firmware version of gprsbee.
Thank you everyone. Regards.
