We are designing BLE products based on the Nordic nRF52840 chipset and star network topology which are used indoors, according to the network structure, we use one Master Unit and max. 19 slave devices in one network. After those devices are paired together, the Master unit would keep connecting with the other slaves devices, once one devices(device A) is losing the connection, the Master Unit would try to re-connect.
However there is still some devices could not be connected for long distance or big signal loss through the walls or floors. To solve this problem we would like to make one repeater which also adopt the nRF52840 chipset and connect the Master unit and the device A to make sure that the device A could keep a stable connection with the network.
The basic idea is based on this scenarios, and the repeater would include 2 parts: slave part for the Master unit and master part for the slave device A, it could adopt either two nRF52840 chipsets which work in master and slave state separately or one nRF52840 chipset which switch between master and slave state alternately.
From our understanding this repeater would introduce one master inside the original star network, this is one extend star network, it is feasible theoretically still?
So the question from us is:
- Is it feasible to use this kind of repeater inside the star network?
- If yes, which solution should we adopt?
- two nRF52840 chipsets, one work in master and the other one work in slave state separately;
- one nRF52840 chipset which switch between master and slave state alternately.
- Is there any more valid solution for this application or SKD etc.
