[BUG] Master/Slave doesn't work with SAT>IP servers (satipc module)

[lars18th]

Hi @catalinii ,

When using the parameter -S --slave with the satipc module (with the -s --satip-servers) the control of the SLAVE tuners doesn't work. In fact, no control is running, so with a simple -S 1:0 and two different SAT>IP servers, the parameter has no action.

As I've discovered, that the problem appears when the adapter is initialized. The code seems to require that the attributes old_pol, old_hiband and old_diseqc of the adapter/master are set. However, these values are only initialized in the function dvb_tune(). So for satipc adapters these values have the default -1 value. And then all checks of the function compare_slave_parameters() fail.

Any idea to fix this?

Hi @catalinii ,

From my point of view the function satipc_tune():

minisatip/src/satipc.c

Line 1438 in 8560d85

int satipc_tune(int aid, transponder *tp) {

requires to add some MASTER/SLAVE checks, like you do in the function dvb_tune() when call to setup_switch() like here:

minisatip/src/dvb.c

Line 640 in 261069a

if (ad->master_source >= 0) {

However, as this code is yours I prefer you provide a solution. My environment is using more than one E2 boxes running minisatip as the SAT>IP server connected to the same wire. So I'm running another central minisatip instance in my Linux server to drive all of them at the same time. So, I need to control the MASTER/SLAVE mode over the satipc module.

Please, can you help to fix this miss implementation?
Thank you.
