programming MESH NRF52832/NRF52840 using SDK nrf connect 2.1.0
Budget: $750 – $1,500 USD
Hi.
I have a custom board nrf52832/nrf52840.
I need to implement MESH topology
I need the NODE do the following:
1.- Enable two digital pin as ON OFF and enable two ADC to read the temperature (NTC sensor) , and sends the temperature to server NODE.
2.- Get the vibration from accelerometer (lis3dH), xyz, config the accelerometer, 2g, 5kHz, MCU feed matrix of 4096 datas with x,y and z axles datas
Make a averange of the each axle vibration, and sends the data to the server NODE
3.- Get the Sound from Microphone, get the sound using DMA config, configuring to get matrix 1024 datas using capture 50kHz
Make a averange of the matrix of sound and sends the data to the server NODE.
4.- Enable GPIO as digital input to measure pulse by some part of the time. the counter must be Send to server nodes.
The server node when receive the information from nodes, it must be printed by UART in the terminal, I have to see the data using Termit in the PC. the printer data must be MAC of the sensor node and two Temperatures values, average of vibration per axle, averange sound and cuantity of pulses.
Now a have this firmware working in the NRF52840 but in the Older SDK NRF 16.0.0.
thanks
