multi-central limitation

[Avi]

I am using the UART multi-central example (from GITHUB) and connecting multuple peripherlas each streaming data at 38K

The multi-central is gathering the data from the various peripherals.

I noticed that if the data throughput is high, the multucentral device cannot handle it and crashes.

What is the limitation of the multi-central? How much data/ peripherlas can it connect and get data at which rate?

I found the following answer few years ago related to SDK15, but the description of the problem seems similar.

https://devzone.nordicsemi.com/f/nordic-q-a/47372/ble_nus_c_evt_nus_tx_evt-has-handle-of-0xffff

I am also getting 0xffff

I am using now, SDK17.1, is there a similar fix or is it a different case?

Problem solved by clearing the echo
