Thank you Petter,

still i wonder why it is 25 times slower when writing with response and why it is not slower when writing with response with competitors - not really a competitor from my point of view ... - product.

Anyway i managed to get almost 100kbit/sec which is what i needed to achieve

cheers

Fabian

Great that you got it working. Great if you could accept my answer by clicking the grey circle with a check mark in it.

With write command/write without response you can send multiple packets in a connection interval. With write request/write with response you can only send one packet in a connection interval. It will have to wait for the response before it can send a new packet.
