- I have been asked if I could enable "Frequency Hopping"
Right now I already fail to bring up a second TRX with OpenBSC. I start 2 instances of "osmo-trx" with 2 differents IP-Addresses but the same port, after that I start "osmobts-trx" with the "-t 2" parameter. OpenBSC seems to see both USRPs but the LED'S an the USRPs indicate that only one is completely powered up and transmitting (a quick check with an Motorola with RSSI also shows only one ARFC). So how do I have to start "osmo-trx" to enable transmitting on both URSPs as TRX0 and TRX1 in one BTS? After that, is it possible to configure "Frequency hopping" with this
setup?
(Because when I changed the value "hopping enabled" of the timeslots in open-bts.cfg to "1" I get a message that this type of BTS does not support hopping)
Using two osmo-trx's or two devices with a single osmo-trx is not supported at this moment and there are no current plans to support this configuration, AFAIK.
That said, we're working on supporting frequency hopping with a single device. I expect this to be ready for testing in the next few months.
