Hi team,

Here's the request from the customer:

Can CC2640R2F implement frequency hopping?
Which function is configuring the parameters of frequency hopping?
Is there any way to make bluetooth transmit reliably even in relatively congested channels?

Could you help check this case? Thanks.

Best Regards,

Nick

Hi Nick,

1- Yes, when using Bluetooth Low Energy, frequency hopping is enabled.

2- Frequency hopping is a mandatory feature of Bluetooth Low Energy. It is always enabled. The application can read (HCI_LE_ReadChannelMapCmd) and change the channel map if needed (HCI_LE_SetHostChanClassificationCmd)

3- Bluetooth LE protocol enables various fault detection and mechanisms transmissions to maintain as reliable as possible communication including in busy environment.

I hope this will help,

Best regards,
