Sensor not working

[magnum3131]

Hi,

I'am trying to make working your sensor example but my flysky Radio doesn't display anything.

The sensor Trame is well detected withe the trame 0x04, 0x81, 0x7A, 0xFF but after i nether received the PROTOCOL_COMMAND_TYPE: // 0x90, send sensor type

My card ESP32 with serial2, Radio Flysky NB4 and FGr4S rx

switch (buffer[0] & 0x0f0) { case PROTOCOL_COMMAND_DISCOVER: // 0x80, discover sensor cnt_poll++; // echo discover command: 0x04, 0x81, 0x7A, 0xFF stream->write(0x04); stream->write(PROTOCOL_COMMAND_DISCOVER + adr); chksum = 0xFFFF - (0x04 + PROTOCOL_COMMAND_DISCOVER + adr ); break; Any idea ?

Thanks
