EU868 FSK RX unstable

Semtech Transceivers SX126x family
#1

Hi,

I am testing my project with sx1262 for EU868 + the redwood tool.
I am using sx1262 driver from https://github.com/ARMmbed/mbed-semtech-lora-rf-drivers
But when I set DR7 and set confirmed or send mac command to RX1, the node can receive data sometimes but also RX CRC error happens or RX timeout occurs.
Could anyone give some idea that I can debug for this issue?

Thanks.

Hi,

Could you please check that you are opening your RX windows with the right timing? The easiest solution is to monitor power consumption with an oscilloscope

Thank you for the suggestion.
The rx window timing seems fine.
I found that the bandwidth was a kind of an issue.
sx1262 driver is using 46.9 kHz but when I change it to 58.6 kHz, it works much better.
