<div>You say that using jolly/testing branch it is possible to use two phones. I am not sure how to use two phones and connect and how is the sync b/w them. Can you please give some brief idea before you write documentation. </div>

</div>pcu master is ok (everything merged).<br>
openbsc master is ok.<br>
bts gprs-work? i don't know this branch, please use jolly/trx.<br>
osmocom_bb you should use jolly/testing branch, because you need to use<br>
two phones, one for broadcast and one for timeslot 1 (gprs). i think i<br>
need to write a documentation for that. but in your case, the IMM.ASS<br>
problem must be solved first.<br>
