Hello,
I am developing an extension for an existing application, so I would like to do as less changes as possible. My application, based on TI CC1310 and the relative SDK version 4.10, consist basically in a concentrator which is connected to the power grid and some peripheral devices which uses batteries. The network uses normal SubGhz communications (not long range mode now) using a polling system, so that the concentrator send a request message to the peripheral device, which answer. In order to minimize the peripheral power consumption we use a really small Rx window running a carrier sense command (2 mS) and, only in case we sniff a preamble signal, we actually trigger the Rx command on the peripheral device. In order to achive this (reliable communication with a CS of 2 mS every 250 mS) we are using a really long preable when transmitting the polling command from the concentrator (we use the TX_ADV command togheter with its preTrigger field) but apparently this doesn't work for the long range mode.
Is there any alternative or is it possible to know what's the technical limitation for long range mode about long preamble, so that we can calibrate the Rx time?
PS: I know that in LongRange mode there is no preamble, a reversed SyncWord is used instead and repeated M times, I call it preable for simplicity reasons.
