Thanks for this case. I also have the same solution! Is that, also, for an OBDII device? If so, the way that I've had to deal with dropped notifications is to instruct the ELM327 to send notifications with no headers (ATH0) and then use the first character as an index to position that set of conver...

Many thanks (also for the great port of MP!). So, short answer is - not yet

This is for @russ_h (Russ Hughes) whose brilliant version of MP for the ST7789 (and ILI9342C) I'm using. There is a method for setting a pixel color but not one (as far as I can see) to determine the color of a pixel. Is it possible to do that? Having a quick look at the C code (which is way beyond ...

After a lot of trial and error using both aioble and basic ubluetooth I have had sufficient success for my purposes. The main problem I experienced (and still experience to an extent) is the processing of multiple notifications. Fundamentally, aioble is not fast enough and basic ble is - just. One p...

Yes, that has worked for me as well. How simple and obvious these things are when you know! - Thanks

I have a hex string: mystr = b'FFF7E7FF704268426803FF380E53131212121312000012BB01BA3300008200016D9E00016C790000865D00008206003723630D016E0271027103E8' and want to get the int value of mystr[44:46] - it should come to 18 In python I would do int(mystr[44:46],base=16) but that doesn't work in MP. I've...

Thanks for this. I've found .../modbluetooth_nimble.c but can't (yet) find where the constants are set. However, at this stage, recompiling MP is probably beyond me and so I'll explore other options first

Yes! Thanks. That and having on the server have sorted the problem.

The MP 1.16 uBluetooth document lists an irq connection update event elif event == _IRQ_CONNECTION_UPDATE: # The remote device has updated connection parameters. conn_handle, conn_interval, conn_latency, supervision_timeout, status = data Is there any way (preferably using aioble) that I can change ...

I'm trying to develop a BLE client to get data from an OBDII reader. I have an ESP32 client derived from ble_simple_central.py working to an ESP32 peripheral derived from ble_simple_peripheral.py (but which I cannot get to work with the intended OBDII reader). I am now trying to use @jimmo's aioble ...
