Recently i bought a TTGO ESP32 oled lora module (868/915 MHZ) and tried to connect with the gateway.</p>

<p dir="auto">As far is i can see in the log parser, the node sends a "find parent ping" to the gateway, which sends the response as a "pong" back to the node. But the response is not received by the node, so they do not connect.<br />
I had to use the newest version of mysensors in order to be able to upload it to the ESP32.</p>
<p dir="auto">Any ideas on how to solve this issue?</p>
