Re: Unable to read from BME280

@dldtechnology That is an interesting find! One would think that when you write to the register, the data will latch :) And I did not read anything in the bus specs to give the idea that such check should be performed. Another issue that I'm looking at is clock stretching with some slaves to timeout...

Re: RTCWDT_RTC_RESET symptom of what kind of error?

This could be caused by bad power to the module as well. Make sure you have good 5V 500mA+ power going to it and that the cable used is good. When radio boots, there is a spike that will cause brownout if the ESP does not get enough power.

Re: Option to disable HAL mutexes

you should disable mutextes by changing the option in tools/sdk/include/config/sdkconfig.h which is generated by menuconfig when libs are prepared in IDF. I will add it as option to the boards soon also. If you use Arduino the usual way and do not spawn threads or run code on both cores at the same ...

Re: BLE implementation expectations?

ESP32 Arduino currently comes with BLE support from IDF. Expect soon an Arduino-like class for easier access.

Re: I2C example wanted

Yes, Arduino code has a bit different(simpler) requirements to run and as such implementing ISRs and other hardware trickery is pointless.

Re: Need help regarding UART1 and UART2 communication for ESP32

Ritesh, you can look into HardwareSerial.cpp as well and see what happens when you start arduino Serial :) it's pretty straight forward. #include "esp32-hal.h" uart_t* uart1; bool startUart(uint32_t baudrate, int8_t rxPin, int8_t txPin){ uart1 = uartBegin(1, baud, SERIAL_8N1, rxPin, txPin, 256, fals...

Re: Need help regarding UART1 and UART2 communication for ESP32

@rudi I especially committed a change so you can safely include Arduino.h in C files as well
