two-way communication?

by kjkoster Mon Aug 15, 2016 11:34 am

Dear All,

On (slide #8) Nicolas Lesconnec mentions that two-way communication is possible. I cannot find anything related to sending data from the server to the device in the documentation. Can someone please point me to the relevant documentation for getting a message from the server to the device? Is that sent as response to a device message?

Yes, this is the so-called Sigfox "downlink" feature. As the device is not listening all the time for power consumption reasons, it only listen to messages from the network after sending a message with an acknowledgment request. This is detailed under the etry for the "AT$SF" command in the module's user's manual. When using the C API, you can refer to the "examples\rf\sigfox_downlink\src\sigfox_downlink.c" example within the SDK sources.
