Hi all.I'd like to ask some direction about a product I want to develop.
My customer has some sensors distributed along his manufacturing plant and has plans to implement all equipments inside an automation project.As could use a lot of sensors (4-20mA), instead buying a lot of analog input PLC cards maybe use BLE Mesh devices can reduce his costs for not buying PLC cards and infrastructure installations.What I ask is, as nRF52 has BLE Mesh, Thread and Zigbee which protocol should I consider and why?Consider I must use Siemens PLC's (S7-1200) to control his plant and equipments, which way could be implemented a gateway BLE Mesh to communicate to those PLC's?
Very useful link.Zigbee was my first choice too.Now I take into the possibilitie to use BLE mesh.There a lot o things to evaluate.Developing a new device (BLE or Zigbee I don't know yet) or use off the shelf devices from big companies.ThanksBest Regards.
I thought Zigbee was good in the industrial space as well, but most of those who could have used Zigbee have gone 802.15.4 + proprietary stack instead of Zigbee.
