Today I learned that WiFi and Bluetooth LE could NOT be used simultaneously on Arduino boards featuring the ESP32-based u-blox NINA-W102 wireless module, impacting the Arduino Nano RP2040 Connect, Arduino MKR WiFi 1010, and Arduino Nano 33 IoT boards. It’s a long-running problem since the first Arduino board with NINA-W10 was introduced in 2018, and meant you could use WiFi or Bluetooth LE, but not both simultaneously. The good news is that the issue has finally been fixed, thanks to a new firmware for the module and new WiFi and BLE libraries. More specifically, you’ll need the following libraries and firmware: WiFiNINA library version 2.0.0 or later ArduinoBLE library version 2.0.0 or later NINA-W102 firmware version 3.0.1 or later The libraries can easily be updated in the Library Manager in the Arduino IDE, and the firmware needs to be updated with the Firmware Updater Tool in Tools > WiFi101 / […]
