Hi,
I am using the STM32WL55JC1 Development Kit. My project includes:
- Many transmitters read temperature every 15 minutes and broadcast data.
- Repeaters that forward the data to the gateway using a mesh topology.
I want to avoid data collision and achieve at least 99% reliability.
I tried the LoRa ping-pong example, and it works for a single hop. But I need a mesh system without collision.
Can you please suggest:
1. Best wireless technology (LoRa, FSK, etc.)
2. Firmware libraries or examples for a mesh network
3. Hardware recommendations (boards or antennas)
