I have a SIM868 module and I have successfuly ran my application on it using SDK_1418B01SIM868M32_EAT.rar downloaded from simcom.ee. Everything works fine, however, I would like to add some Bluetooth features to it. According to the official documentation, it should support Bluetooth, it even has a pin for a BL antenna, but when I try to run any BL related AT commands on it, all i get is ERROR.
When I flash 1418B02SIM868M32_BT.ZIP on the chip, Bluetooth AT commands work, but my app isn't loaded. I found out that there is an EAT with Bluetooth for the SIM868E chip - 1418B02SIM868E32_BLE_EAT.RAR Even though it is not ment for the SIM868 chip, I flashed it anyway, but it didn't work.
So my question is, is there an EAT with BL functionality for the SIM868 or is there a way to modify the existing EAT files to enable BL?
