piratebox with mikrotik

Hello everyone
is there anyone that has experience with a mikrotik groove on a (raspberry pi 1) piratebox ?
i have a piratebox for a while now
and i want to "upgrade"it with a mikrotik groove a 52hpn for more coverage
but i cant get it to work .
i have the mikrotik configured as a bridge ap
and changed a few things in the piratebox.conf as discribed on the mods webpage

i can see the newly created ap but i cant connect to it
only if i plug another wifi module into the piratebox i can connect to it over the newly created ap on the mikrotik

what im i doing wrong ?

here i some extra information about the configuration
this is what i changed in piratebox.conf :

DO_IFCONFIG="yes"
USE_APN="no"
#
act like dns&dhcp (dnsmasq)
USE_DNSMASQ="yes"
INTERFACE="eth0"
# On which interface DNSMASQ should listen. -i is the parameter for dnsmasq
# Make it empty to disable
DNSMASQ_INTERFACE="eth0"
#Brdige add interfacce (setr yes to enable bridging)
DO_BRIDGE="no"
BRIDGE="br-lan"
#Network
NET=192.168.1
#IP-SHORT (is stringed together)
# Which IP is your Box?? i.e. 1 => 192.168.77.1
IP_SHORT=1

and this is my mikrotik config:

mode = ap bridge
create new bridge with
interface to Ether 1 and bridge to Bridge 1.
and interface to Wlan 1 and bridge to Bridge 1.
