Importante note : the addressed mode must be activated in order to use the secured mode. 3.2.1.4 Transmission integrity control The RF protocol includes a 16 bits CRC. Each data extracted from an RF packet with an invalid CRC is silently discarded by the module state machine. -
Page 18: Addressing
NARROW BAND - NB868 - User guide version V2.2.5 - Software version V2.3.0 An RF transmission can starts according following evens : • either a timeout (S217) • or a quantity of data in the buffer memory (S218) The first of these two limits reached triggers transmission start. When the number of octets in the buffer memory reaches the threshold of register S218 before the timeout of register S217, it is triggering on data. -

Page 25: Soldering Curve
NARROW BAND - NB868 - User guide version V2.2.5 - Software version V2.3.0 Considering the components on the module, we can define the module as a level 3 component, whose floor life under 60% max RH is 168 hours. Having in mind that module to mother board assembly delay is not under control, same for temporary storage atmosphere, the best solution is to dry the module after test and put it in reels and then pack them in MBB bags.
