ESP32 with WH65B

[pcfritz]

Current Situation

Hello, thank you first of all for the great work!

I am trying to receive and decode the weather data from the WH65B, unfortunately I am not succeeding in either. I have a cc1101 connected to my ESP32, but unfortunately I can't receive anything. In addition, I have tried a door contact switch, which works.

Am I making a mistake? Thanks in advance!

Did you see this in the closed issues - #102

[pcfritz]

Thank you, I have. However, I had understood that the fix only applies to SX1278, I use the CC1101 chip.

[NorthernMan54]

It applies to both

Hi @pcfritz

Not sure if you have already solved your issue, and this can be closed, but be aware that if your WH65B is a 868MHZ version you need to set the frequency to 868**.35**MHZ, e. g.

'-DOOK_MODULATION=false' ; FSK modulation activated
'-DRF_FREQUENCY=868.35'

Hi, @NorthernMan54, a long time has now passed, and the project has briefly faded into the background. However, the problem as such still exists: I am currently testing with a Bresser 5in1 station, which works wonderfully with the Lilygo on 868.30:

Now I wanted to try the same with CC1101 868 mhz receiver on an ESP32. I use this config:

[env:esp32_cc1101]

monitor_speed = 921600
upload_port = /dev/cu.usbserial-537E0451031
upload_speed = 460800

Unfortunately, I only get the result:

Have I made a mistake somewhere?

Edit: I am using a TTGO TCall Sim800l.
