The field 'Radio addresses of the repeaters used' can have a size of 6, 12, or 18 bytes, according to the
number of repeaters used.
Remark : maximum size definition
- Point to Point mode
:
Max = 152 bytes of data
- Relaying mode : Max = 152 – (2 + 6 x Number of repeaters)
=> 1 repeater : 144 bytes of data,
=> 2 repeaters : 138 bytes of data,
=> 3 repeaters : 132 bytes of data.
