Error: "__digitalRead(): IO 19 is not set as GPIO.", even with example code

[PKeidel]

Hi,
I am trying to use a C1101 to receive values from my water meters.

While testing with the most simple example "c1101_New_Receive_method_minimal" and the default pins, I got the following esp32 error:

[ 13][E][esp32-hal-gpio.c:190] __digitalRead(): IO 19 is not set as GPIO.

Is this problem already known?

I added some logging to "SmartRC-CC1101-Driver-Lib/ELECHOUSE_CC1101_SRC_DRV.cpp" and the pinMode() calls in ELECHOUSE_CC1101::SpiStart do look correct.

  Serial.printf("SpiStart() outputs= %d, %d, %d; inputs:%d\n", SCK_PIN, MOSI_PIN, SS_PIN, MISO_PIN);

Prints: SpiStart() outputs= 18, 23, 5; inputs:19

I'm having a similar issue, have you figured something out?

[PKeidel]

I had no success. But a different error. Now I get:

E (1637) gpio: gpio_set_level(227): GPIO output gpio_num error
[  1652][E][esp32-hal-gpio.c:102] __pinMode(): Invalid pin selected

@panaak @PKeidel @LSatan
any news on this topic?
I have the same problem in combination with Arduino V3.0.7 and ESP32

for all SPI PINs I get errors like this:
[esp32-hal-gpio.c:190] __digitalRead(): IO 19 is not set as GPIO.

but in general it seems to work. I can receive already some data, even with this error messages.
