1. Sort out power issues: our device (with 2 nRF MCU and sensors) will be power from the LED driver (SR, DEXAL, or other DALI part 150/250 / ANSI C137.4-2019 compatible LED Drivers). The connection is only 2 wires providing both power (~15v) and the data/signal to the LED Driver. Prototype the power converter on a breadboard to measure power parameters (volt and mA availability). 2. Develop the schematics / circuit design for the device with PIR and light sensor connected to the LC MCU. There would be basic version (no physical communication between the 2 MCU) and an option to connect the 2 MCU with proposal for Pin-out/in using preferred method (serial, SPI or I2C) and suggestion for a protocol. 3. Develop the prototype using one nRF52-DK (or equivalent), one nRF52840-DK (or equivalent), breadboards for sensors etc. 4. Deploy our BLE mesh FW from Silvair to the nRF52832 and our BLE FW from Meshtech to the nRF52840. 5.1 test the prototype: the LC MCU with a LED driver and a BLE mesh wall switch and the inbuilt sensors. example of a wall switch: [login to view URL] 5.2 test the prototype: the IoT MCU with 2 sensors. example of sensor: [login to view URL] 6. PCB design. The goal is the get a small form factor as explained in the documentation provided. We have a prototype with one nRF on each side so we are looking at a similar design. For every step above we are looking for sound judgment on the solution and we have a partner locally that can help review and provide input. Unfortunately, the partner is very busy with there own development so they don't have time to do this project for us. However, they are available for consultation and provide input and suggestions

Hi, I can help you from step 1-6. 1. I will help you choose proper Regulator for your MCU needs. let me know about the details. still not clear on this step. 2. I can help you make prototype in this step. I need to know what is LC MCU you mention. 3-4. sure. I have NRF52832 in my desk that we can use for prototype. I have built it before. so it's not a first time for me programming NRF5 mesh protocol. 5. I can help you on it. 6. I have 8 years experience as PCB designer. I can build you Multilayer PCB with more than 2 layers. I have built several NRF5 PCB before, So I know how to design it properly. Let's discuss the details over chat. let me know your thoughts. Best Regards, Rijal

I've got a lot of experience with LEDs so I can do for you no problem. I have a fully featured lab which allows me to completely make a functional prototype for you. I am located in canada so you don't have to worry about receiving your prototype. I make all design files available on github. My lab includes a state of the art oscilloscope which allows me to debug at the highest level. More than 8 years experience.
