Re: Can't get esp_ble_gattc_read_char to trigger ESP_GATTC_READ_CHAR_EVT

1) Yes it is readable
2) No because I've read it from some other devices without bonding
(I wrote the server's code as well so I know how it is configured)

As I've not received any response here, I've also cross-posted to https://github.com/espressif/esp-idf/issues/4839 which also points back to here.

Re: Can't get esp_ble_gattc_read_char to trigger ESP_GATTC_READ_CHAR_EVT

Is the problem that I'm trying to read more than 1 characteristic on a connection? All of the examples seem to show 1 connection, selecting one service and then reading one characteristic value. How is the state machine supposed to work when I want 3 services and read the characteristic value form e...

Can't get esp_ble_gattc_read_char to trigger ESP_GATTC_READ_CHAR_EVT

I think I'm using the latest released version of ESP-IDF (I must admit that it is very hard to find exactly which version I have installed - all I see is references to the GIT repository but which version actually is 'stable' I have no idea: I think there should be a version number is at least one c...

Re: ESP-IDF V4 on PlatformIO

OK - probably my mis-interpretation of the last post in https://community.platformio.org/t/how-to-use-esp-idf-current-version-from-https-github-com-espressif-esp-idf/4598/14 where they do actually say they don't integrate beta releases (my emphasis of the work I managed to skip over). I'll take this...

ESP-IDF V4 on PlatformIO

Now that ESP-IDF V4.0 has been released (and thank you for that), is there any word on when a version will be released that can be used on PlatformIO? I've written code that needs some of the new V4 BLE API but when I have tried to copy the previous V4 development versions to PlatformIO, I've ended ...

Re: SPI Master Slave handshake with spi_device_queue_trans

I might be wrong here but I suspect you are thinking the SPI module operates in the same was as the UART. In a UART you can have separate send and receive operations - they can even overlap (i.e. send while receiving). With the SPI module, you *exchange* values - the master controls when the exchang...

Re: Synchronizing SPIs

Got it now - you are talking about Quad SPI (QSPI)

Re: Synchronizing SPIs

Now I am more confused. SPI is a serial exchange protocol which means that each bit of a value being sent is presented to the MOSI (for a master - MISO for a slave device) pin in line with the SCK transitions. Therefore I have no idea how this relates to the gpio_matrix_out function. You don't menti...
