"To reduce this, try reducing the channel tab size to for instance 3 channels on device and host." Thats it. Thank you, now i have only 4ms burst current:)

Hi,

When you're sending data just once in a while, like 1 time per second or every minute, the gazell protocol will not be able to keep sync properly and you will get re-transmits due to the device trying to "hit" the hosts listening channel.

7 re-transmits sounds normal in such a scenario, depending on what the channel tab size you're using.

To reduce this, try reducing the channel tab size to for instance 3 channels on device and host.

You can get caps in a very small package (0402) in the low micro-farad range. We recommend not having more than 100 mV drop on VDD, so you're on the right track.

Cheers, Håkon
