Does the BL654PA or BL5340PA have EU Regulatory certifications (CE/EN)?
The BL654PA module has not been certified in EU as
regulatory restrictions limit TX Power spectral density to +10dBm/1 MHz. The
same requirements are true for the BL5340PA, but this module will achieve regulatory approvals in the EU with TX Power set below +10dBm.
Operating a radio device in the 2.4GHz frequency band there
apply certain regulatory requirements with regards to the maximum usable TX
output power. It ultimately comes down to the RF power spectral density instead
of a flat maximum TX power value.
ETSI EN 300 328 technically allows for 20dBm RF output power
for equipment when Adaptive Frequency Hopping (AFH) and at least 15 channels
are available. The only limitation is maximum 20 dBm for equipment meeting
these requirements. However, the Nordic SoftDevice or nRF Connect SDK
SoftDevice Controller does not provide a means for AFH. In this case the Power
Spectral Density must be tested which limits the maximum radiated power to
10dBm/MHz.
While technically it would be possible to offer a module in
the EU that can operate >10dBm, there are many hurdles in implementation
that would increase development effort and cost.
