Time of flight wireless sensor

We are looking for a wireless sensor PCB layout and firmware to drive it.

The device should use the eRIC-LoRa radio module from [login to view URL], to transmit distance measurements, measured by ST's VL53L0X sensor.

The device needs to have a low cost ARM MCU, be powered by a non-rechargable AA 3.6V lithium battery (already sourced), RA edge mounted SMA connector for the antenna, read switch to turn on/off the device and reset, single LED to show when been turned on initially, when 1st reading had been made, and when transmitting, programming via FTDI USB chip onboard and USB Micro B connector.

The operational profile should be.

- Readings - Take a sensor distance reading every 1 minute and log locally.

- 1st Reading - The distance of the first reading after 1 minute.

- Transmit - Transmit a simple summary (Min/Max) of the sensor readings every 1 hour.

- Alert Transmit - If the sensors reading is more than 5% than the first reading, send a message every minute until reed switch has been activated.

- Alert mode - The device should be transmit only but when in alert mode, it should wait for 2 seconds after each transmission of the alert message, to receive an inbound RF packet from a gateway to reset the device.
