certification nrf52840 ETSI EN 300 328 V2.2.2 spirous emission channel 0 and channel 79

[alexandre trilles]

Good morning,

The laboratory ask me to put BLE module in emission channel 0 (2402Mhz) and channel 79 (2480Mhz) with GFSK 1Mbps. And after to be able to put in reception the module in channel 0 after channel 79. 

• CMin (2402MHz) and Cmax (2480 MHz)

I use the RAYTAC module with the nrf52840 chip and I use s140 nrf52 7.2.0.hex softdevice. The RAYTAC module is already certified FCC/CE ! 

Do you have functions to make it ?

Is it really necessary to force the module on these min and max channels, knowing that the module is at +8dBm !

I must to start the certification in Laboratory the March 13.

thank you very much for reply

where can we find information that explains the location of this initialization and how zephyr is launched?

See Shell doc.

I understood the shell is a Zephyr's service then at what moment we load Zephyr and the shell (.conf, .overlay file )? 

This post might help.
