S2-LP transceiver, STEVAL-FKI868V1:

it has a feature 'Automatic acknowledgement, retransmission, and timeout protocol engine".

1. Does the acknowledgement automatically come from receiver?

2. Does this feature automatic for S2-LP transceiver or it may be enabled/disabled programmatically?

3. If I want to use a few receivers, is it possible to disable this feature or enable it only for one receiver, which is placed on the longest distance?

It depends on your mode, if you are using STack it does an automatic acknowledgement. If you don't want an ACK then use a basic configuration similar to the GUI.

Hi N.Vadim,

1. Yes, if automatic acknowledgement is enabled
2. Yes, please enable with register PROTOCOL0, bit 2
3. Yes. please refer to the DK S2LPLibrary_Examples, STack LLP example

in SDK_StackLlp_B.c it enables the auto ack by default (line 379): S2LPPktStackAutoAck(S_ENABLE);

Please modify according your needs.

Best Regards,

Winfred

Hi Winfred,

thank You very much,

it's rare to see such answers - all according to the questions and nothing redundant.

And it was very usefull for me to get the names of libraries and examples and ever line number in c-file !

Best regards,

Vadim
