How BLE & 2.4G Proprietary work together?

[EthanZhao]

Hi there,

I have an smart product that will use both BLE & 2.4G Radio. There are few question about framework.

1. I saw radio packet contains such as S0 S1 ADDRESS etc.....    Does BLE framework use the same radio packet?

2. Is there have any way that both mode can use in the same time?

thanks~

Hi

1. I think the S0 and S1 fields are described well by Dmitry in this ticket:   RE: S0 and S1 fields . Yes, BLE also uses these fields.

2. Since there is only one radio on the nRF52 (and nRF53) series devices there is no way to use Bluetooth Low Energy and a proprietary 2.4GHz protocol at the same exact time I'm afraid, but you can do timeslotting to have both BLE and a proprietary protocol run concurrently. You can check out my colleague Hung's tutorial on timeslots here for example. It is an old tutorial at this point but the general idea is the same. There was also made a blog post to do ESB and BLE concurrently here.

Best regards,

Simon
