Connection via WiFi instead of cellular

[terdt]

Hi René, if understood it correct the MQTT messages will be sent via GSM or LTE to the broker. Is there also a possibility that I can use a normal ESP without cellular modem ? The ESP should connect via WiFi to an Hotspot / AP. Background ist that I plan to use it an RV (Wohnmobil) where an WiFi Network already exists. Kind Regards Thomas

Hi Thomas, this isn't possible because Bluetooth and WiFi shares the same frequencies. ESPs used with arduino framework does not realy work with coexistence. This should possible with the espidf framework, but the most of used libraries wouldn't work with this.
