Hi.
Probably wrong phone number or API key. Double-check those.

I want to learn: With Esp32, can esp32 Bluetooth coverage area send messages to all mobile phones? Mobile users will not give their mobile numbers. Example: Can information messages be sent to the WhatsApp accounts of the participants in an event? Thank you in advance for your interest. .

Howya,

Check your phone number. I had same error code

Error sending the message
HTTP response code: 203

Then I noticed that I have an extra number( fat fingers on keypad 🙂

Also I tried my missus phone number to send her “hearts” 😀 from ESP32

Same error code. Must be related to phone number, I guess.

Good luck
Stef
