SCAN 1MPHY&codedPHY ADVICE

[jermi]

When scanning 1MBPS & Coded PHY at the same time, the probability of Coded PHY broadcast scanning is very low, and 1MBPS PHY broadcast can be scanned normally
Slave configuration:
   5 terminals are configured as Coded PHY (broadcast once every minute for 5 seconds and the broadcast interval is 1 second)
   13 terminals are configured as 1MBPS PHY (broadcast once every minute for 5 seconds and the broadcast interval is 1 second)
Host parameter configuration:
   Scan interval 2.156s (3450 * 0.625ms)
   Scan window 1.067s (1707 * 0.625ms)
Test situation:
   Scan Coded broadcasts individually, which can basically ensure that each device is scanned at least once every minute
   Scan 1MBPS broadcasts separately, which can basically ensure that each device is scanned at least once every minute
   Scanning two devices at the same time, Coded broadcast is difficult to scan, 1MBPS broadcast can basically ensure that each device is scanned at least once every minute

Please help：

1：How to scan coded & 1mphy at the same time
2:  when SCAN 1MPHY&codedPHY ADVICE ， Is it a polling scan or a periodic scan based on the scan interval,

thanks ！！！

Hi

Can you explain what you mean with "Only a small part coded can be scanned"? Does that mean that just some of the devices are appearing, or that just a small part of the advertisement appears? In the latter case, that means that you're only scanning on the primary channels, and are not seeing the Coded PHY advertisements on the secondary channels.

Best regards,

Simon

Hi Simonr:

    CODED and 1MPHY advertisements are broadcast once every 1 second. The scan results are shown in the figure below. Why is CODEPHY scanned much less than 1MPHY? Codedphy takes almost 30 seconds to be scanned once.

    scan parameter configuration:   Scan interval 1.7 second ，   Scan window 5.1second

thinks！！！

sorry，I Forget to tell you， This host  has a link as a slave with the phone while scanning。
