Further to Ben's suggestion... It's worth opening a Comms port to the esp32 and checking if there is any useful debug info.
It can be things like wdt, spi rate not supported etc

Is there a sample program in the espressif framework - if so, it might be possible to leverage that to do what you want. Or see https://github.com/nopnop2002/esp-idf-wifi-apsta for example. Most (all?) of these samples require callbacks - however they are fairly easy to implement in Flowcode (just p...

Just tested - and yes. The results look sensible... Saving buffer 0 - (182,1678,-16281) Saving buffer 1 - (154,652,-15675) Saving buffer 0 - (-16348,436,500) Saving buffer 1 - (-16326,482,950) Saving buffer 0 - (-34,16344,-922) Saving buffer 1 - (2,16330,-965) With the board 'aligned' in each of the...

Thanks Stefan,

That's very helpful - I'll have a look and see if I can spot the pattern in my sensor's returns.

For interest - I wanted to see if the accelerometer is returning 'meaningful' data.... I added a 'SaveData' macro - although in this case it outputs the first 4 6 value samples from the save buffer to UART... I went with using accel_data[0..499] as buffer 0 and [500.999] as buffer 1. The ReadSample ...

Have you seen this topic?

Hi Stefan, You need the TaskId from xTaskCreatePinnedToCore - to pass to notify.. I think it is the last but one parameter - and you'll need to pass the address of a FC variable.. So if the variable is SaveToSDTask (needs to be a UINT32) - then pass &FCV_SAVETOSDTASK - the 'drag' variable to the...

That's good Have the 'whiskers' disappeared from the trace?
Also can you save the data fast enough?

The Bluetooth might be struggling for processor time - the co-operative multi-tasking isn't given much time here..

Can possibly push a bit faster - using esp_i2c_write_then_read (name from memory) - reduced the delay in the reads. Some thoughts on double buffering.... Assuming a buffer size of 1000 records - increase the receive buffer to 2000 records (note this might be adjusted to suit the 'save' task - maybe ...

I also discovered that you can drag and drop a folder to the forum... If that folder is an esp32 project folder this is very much a mistake ! The majority of the files are rejected (phew) - leaving (just) a few for deletion.
