I have a server in MCPE 0.15.10 but i don't know if i can use packets for transfer to another server? I tested to use TransferPacket but it seens that the function of the packet from this plugins doesn't work anymore, it exists another plugin that does that for MCPE 0.15.10? Whitout being a proxy
no problem. simply that nobody cares about 0.15.10 (possibly "the last version that works") And the answer for your question is "no".
I know more servers working very well in Brazil community they are all in 0.15.10, i don't know if 1.2/4/5 is cool because of bugs i have seen, i know 10 servers in 0.15.10 that is very big and has much players in there playing whitout much bugs, crashs, error, that's because i am transferring to 0.15 the only problem there is transferring to another server, i think if Synapse works.. maybe?
As far as I know, versions as old as 0.15.10 are no longer supported. I think this forum is not some place you would get help from.
