nRF52 max throughput

[ashert]

Hi,

We're using nRF51288 on our product and we're interested to move to nRF52.

We bought the DK (PCA10036) EV board and migrated the code.

We've noticed that the TX fifo on each connection event is limited to 3 packets (compared to 7 packets in nRF51), which dramatically reduces the max throughput.

We also noticed, in the nRF52 documentation (nRF52 Series > SoftDevices > S132 SoftDevice > S132 SoftDevice Specification ->BLE data throughput) that the max throughput of sever notification is 42.6 kbps instead of 128kbps in nRF51.

Is there a possibility to increase the number of packets per connection event?

Thanks.

I'm assuming you are migrating from S110?

The throughput is the same as with the S130 SoftDevice for nRF51, see this. This is because it can be a peripheral and a central.

We plan to improve this. For more information you should contact the RSM for your area, if you don't know who that is please send me a PM and I'll let you know.

Thanks for the answer Petter. you are correct - we're migrating from S110 and want to have the same throughput - what are our options? Are there plans for S110 based SoftDevice for nRF52?
