Hello,

change your method in this way:

- (void) connectToLightstreamer {

_client= [[LSClient alloc] init];

LSConnectionConstraints *constraints= [[LSConnectionConstraints alloc] init];
constraints.maxBandwidth= 10.0;

LSConnectionInfo *connectionInfo= [LSConnectionInfo connectionInfoWithPushServerURL:SERVER_URL pushServerControlURL:nil user:nil password:nil adapter:@"EMISORAS"];
connectionInfo.constraints= constraints;

[_client openConnectionWithInfo:connectionInfo delegate:self];
}

Best regards,

Gianluca
