I'm very new to Arduino development and need some guidance on how to accomplish OTA updates.
I have an iPad program I wrote to connect to the Nano and send commands that control a pump. Everything is working as expected. Before I distribute the device I want to provide a way for the end user to update the Nano BLE sketch via custom code in the iPad program over Bluetooth. At this point I'm looking for some advice on options available to accomplish this. The device will be installed in a vehicle so a wireless update is necessary.
Thanks and I appreciate any and all ideas.
