Opening a session

psvz — Mon, 26 Dec 2022 19:36:40 GMT

Could you please help me to open a session to SE050-E over I2C bus? This is as far as I could get with documentation and examples available:

int main(int argc, char **argv) { sss_session_t sesh; SE_Connect_Ctx_t connectCtx = {0}; connectCtx.skip_select_applet = 1; connectCtx.sessionResume = 1; connectCtx.auth.authType = kSSS_AuthType_None; connectCtx.portName = portName; connectCtx.connType = kType_SE_Conn_Type_T1oI2C; status = sss_session_open(&sesh, kType_SSS_SE_SE05x, 0, kSSS_ConnectionType_Plain, void *connectionData)

And I am stuck with portName. I assume it should be something along the line of "/dev/i2c-1:0x48" but could you confirm that?

Hi @psvz ,

The port name can be fetched from the environment variable of "EX_SSS_BOOT_SSS_PORT", you may refer to ex_sss_boot_connectstring() for details, but for T1oI2c case, you may define it as Null.

Have a great day,
Kan
