Radio data Format with nrf9e5

[pst]

Hello,

I have a problem with the NRF9E5 (cannot be selected in the list).

For several years we have been using the mentioned chip without any problems. Now we want to integrate 3rd Party transceivers

into our systems and therefore we need detailed information about the radio data that is transmitted besides the payload (preable, sync, address, CRC...).

Unfortunately I could not find anything in the documentation.

Could you please provide me with the necessary information   

Thank you very much in advance

Sincerely

Peter

Hi Peter,

 

The packet build up is the shockburst format, which is explained in the nRF9E5 datasheet, chapter 12.2.2, as well as chapter 15..

The physical RF is GFSK, manchester encoded, with a datarate of 100 kBit (50 kBit effectively). More info about the PHY can be found in the el.spec part of the datasheet.

 

Best regards,

Håkon

Hi Håkon,

thank you for your response.

Could you please tell me the exact 10 bit sequence of the preamble and the CRC Polynome.

Best regards

Peter
