Lora 32 RX timeout on 470 band

Having doubts/troubles with LORA 32 and HT-M00 gateway.

Preamble changed to 16, connected to heltec cloud, TX going just fine on the 470KHz while the serial monitor and Live Lorawan frames at the gateway page states RX at different band - 500KHz which most of the time goes to ‘timeout’ status.

TX on freq 471100000 Hz at DR 5
DIO0:TX Done
RX on freq 501100000 Hz at DR 5
DIO1:RX Timeout
RX on freq 505300000 Hz at DR 0
DIO1:RX Timeout

Any suggestions please?

one note - sometimes RX goes OK for a single time after a bunch of timeouts.

different band for downlink is ok according to CN470-510 specs.

allright. read the docs.

the default examples for lora 32 use 7 channels and try to send data randomly to each one and rx works the same way.

as HTM00 a dual channel gateway we need to define only 2 channels in the code for LORA 32.
This is done through
uint16_t userChannelsMask[6]={ 0x0600,0x0000,0x0000,0x0000,0x0000,0x0000 };
In this case we define only 2 channels: 10 and 11 which for TX (HTM00 will be 472. 1 and 472.3)
