It could pose a problem, i never tried without the module.
The last part of the subject is the ble mac adress of the device indeed.
Okā¦ Iām trying again with it hooked up. To make matters worse, the chip I have doesnāt have the pins labeled on the silk screen so Iām not certain where the GPIO pin is that I need to useā¦
Can you tell me where RF_RECEIVER_PIN 13 // D13 on DOIT ESP32 is on this board?
Is it GPIO13 which is at 15?
I checked my receiver module and Iām getting 3.3v so power and ground are correct. Not sure about the rf receiver pin though.
Okā¦ so anytime I have RF enabled I get the panics. I have the module that was working fine on an ESP8266 wired with 3.3V, GND and GPIO13. The chip panics with the module connect or not connected. Iāve set it up for just BT and it is working without issue.
Could you try with other pins, change them into config_rf.h
Yes. Would it be possible for you to disconnect your module and see if it causes your chip to panic? Thanks for the help
Iāve tried a few different pins and nothing changesā¦ Always panics.
Did you tried another board ?
Itās the only esp32 I have. I tried a couple of other example sketches for the esp32 and they run without problem. In fact, OMG works perfectly fine when using BT only.
I tried with an ESP32 alone, with ZgatewayBT and ZgatewayRF uncommented and it works fine:

The board is an ESP32 DEVKIT
This is the board I bought https://www.amazon.com/gp/product/B0718T232Z?pf_rd_p=c2463b52-1139-4aba-9ac9-26d103f6c586&pf_rd_r=7J2RNMYHBCQ6PK5GEHCP
Could you try with the last version from master, there was some corrections implemented by @animavitis
The new code does allow me to run both BT and RF at the same time without the kernel panics. I had to change RF receive to GPIO22 to get RF to work. It appears to be working fine now. Thanks for the help

Hi all,
Iām a new user of OMG.
I installed OMG 0.9.8 on a ESP32 (devkit rev1). Below my custom configuration (Bluetooth and RF with cc1101 transceiver).

;esp32 1

;upload_flags =

; --port=8266
upload_speed = 115200 ;921600
monitor_speed = 115200
But I have an issue. A core panic occurred and the esp32 is resetting.
I followed your recommendations in this topic : i changed the RF_RECEIVER_GPIO value. But nothing changed.
Notice that Bluetooth alone works fine and RF alone works fine too.
Here is the log :

Is there anything I am doing wrong ?
Thanks for your help 
Hi and welcome!
Seems that there is some memory issue, you may have to remove some protocols from rtl_433 so as to free up memory? To do so you could follow this approach.
Could you share the result of the memory and flash after the build?
Thanks for your quick answer. Is this what youāre thinking about :
Linking .pio/build/esp32dev-ble-1/firmware.elf
Retrieving maximum program size .pio/build/esp32dev-ble-1/firmware.elf
Checking size .pio/build/esp32dev-ble-1/firmware.elf
Advanced Memory Usage is available via "PlatformIO Home > Project Inspect"
RAM: [=== ] 25.1% (used 82324 bytes from 327680 bytes)
Flash: [======== ] 78.8% (used 1549244 bytes from 1966080 bytes)
I donāt understand how to remove protocols ? Could you explain how to do that ?
Thank you.
I think you should remove the non interesting ones into these files:
include/rtl_433_devices.h, src/rtl_433_ESP.cpp, and src/rtl_433_ESP.h
But maybe @NorthernMan54 can advise.
I think you should open also a separate topic dedicated to your problem
