# Esp32-simple-radio
Library that provides very simple radio transmission via BLE GAP, inspired by micro:bit's radio.
## Example
Add current version to your platformio.ini:
```ini
...
lib_deps = https://github.com/RoboticsBrno/Esp32-simple-radio/archive/refs/tags/v1.0.0.zip # or newer version...
...
```
```cpp
#include "simple_radio.h"
void setup() {
SimpleRadio.begin(0);
SimpleRadio.setOnStringCallback([](std::string str, PacketInfo info) {
printf("Got string %s rssi %d\n", str.c_str(), info.rssi);
});
SimpleRadio.setOnNumberCallback([](double val, PacketInfo info) {
printf("Got number %f rssi %d\n", val, info.rssi);
});
SimpleRadio.setOnKeyValueCallback([](std::string key, double val, PacketInfo info) {
printf("Got kv %s = %f rssi %d\n", key.c_str(), val, info.rssi);
});
char buf[32];
for (size_t i = 0; true; ++i) {
switch (i % 3) {
case 0:
snprintf(buf, sizeof(buf), "iter %d", i);
SimpleRadio.sendString(buf);
break;
case 1:
SimpleRadio.sendNumber(double(i) / 12);
break;
case 2:
SimpleRadio.sendKeyValue("num", i);
break;
}
vTaskDelay(pdMS_TO_TICKS(500));
}
}
```
