Maximum Advertising Intervall

[Gernod]

Hi,

we use nRF8001 in a custom hardware/software project. The device is battery powered and should use minimum current (in the range of <20µA). When we set the advertising intervall to 100ms (as parameter of the Connect command 0x0F, no timeout) we can detect and connect to the nRF8001 using the Nordic UART and our own android and iOS based apps without any problem.

When we set the advertising intervall to higher value, say 1000ms or more, a scan will detect the nRF8001 as soon as an advertising packet is sent but it is more and more difficult to establish a connection. The longer the advertising intervall the more difficult to connect to the device. This is true specially for android, iOS seems to be more robust.

Do you have any advice of how to improve this behaviour?

Thanks

Yes, it is true that the longer the advertising interval, the more difficult it will be to connect - that is just in the nature of the process.

Do a forum search; it's a frequently recurring topic - eg,
