sriram598/Wireless-sensor-network-using-STM32 ? reverse-engineered prompt

Build me a simple wireless sensor monitoring project using an STM32 Bluepill as the sensor node and an ESP32 as the WiFi gateway.

The STM32 should read environmental data from a BME280 sensor, send the readings wirelessly over an NRF24L01 module, and the ESP32 should receive that data and push it to ThingSpeak so I can see the values live in the cloud. I want the whole flow to be easy to understand and usable as a basic demo for a small wireless sensor network.

Please set it up so it can work with one sensor node now, but still feel like it could handle more later. Include the wiring and code for both sides, and make sure the data format is simple and reliable. If you need to, look up the current ThingSpeak and library docs online so the example is up to date.
