Hi,
Is it possible updating connection parameters from master control panel? I need writing in this characteristic.
Thanks
Hi Francis,
Yes you can! When connected, there is a button named update (see below pitcure). With this you can update the connection parameters during a connection.
You can change the parameters applied when first connecting in file->options->connection parameters. Here you can also set if the central should accept the connection parameter update request from the peripheral and which interval it should choose.
See this video for more information.
You mean the SlavePreferredConnectionParameters? These are preferred parameters, and set in the peripheral code with sd_ble_gap_ppcp_set(...)
. The central howevers decide the connection parameters that will be set for the connection. The peripheral can send a request and if the central does not accept the request, the peripheral can decide to accept the connection parameters from the central, come with a new request or disconnect.
