PSoC 6 MCU

Hello team --

If I have a PSOC 63 BLE connected to another PSOC 63 BLE, one as central and the other as peripheral, and they are communicating with the fastest connection interval (7.5ms), can I also set up each side to be an observer looking for "pings" from a remote acting as a broadcaster?  What would the timing look like between Connection Intervals regarding how the 3 advertising channels will be scanned.

Please let me know if this is possible and what the timing looks like on the radio.

Regards,

Corey

Hello Corey,

If I have a PSOC 63 BLE connected to another PSOC 63 BLE, one as central and the other as peripheral, and they are communicating with the fastest connection interval (7.5ms), can I also set up each side to be an observer looking for "pings" from a remote acting as a broadcaster?

Yes. It is possible. PSoC 6 BLE supports 4 simultaneous BLE connections. They can be any one of the following:

1. Central

2. Peripheral

3. Observer

4. Broadcaster

The 4 simultaneous states can be possible through 4 LL states as shown below:

What would the timing look like between Connection Intervals regarding how the 3 advertising channels will be scanned.

Since the 4 LLs run parallely, the connection interval and advertisement interval will also run parallel and remain unaffected.

Please note that In PSoC Creator/Modus BLE configurator tab you have to select "Maximum number of BLE connections = 2" and select those two roles required.

Please refer PSoC 6 MCU - Firmware Design for BLE Applications application note  Multi-Master-Single-Slave code examples for firmware reference.

Does the observer role cycle through the 3 ADV channels or does that have to be set manually?

Is there a diagram showing how the Central role and the observer role share radio time?

Hi,

The Central/observer by default scans the 3 advertisement channels. It does not need any setting.

Thanks
