high packet loss

hi

i have 2 xbee pro modules (HV 1842) communicating with each other
one of them sends about 10 bytes every 50ms at 78125 baud
in about 30% of the cases i dont get an ack back
both have same channels and 16 bit addresses of each other set
firmware 10CD
API mode

they are lying next to each other
RSSI is at about 0x20 so this should not be the problem

already tried changing channels and RO but did not help

any ideas?

if i connect my bluetooth module to the same power supply im getting <1% packet loss

seems like unstable voltage …

solved :slight_smile:
