Spent 2 days on this, and nothing at all from the UART. I have triple-checked the connections and never get any errors, but not a whisper from the UART :-( BTFW61="micropython/ports/nrf/drivers/bluetooth/s140_nrf52_6.1.1/s140_nrf52_6.1.1_softdevice.hex"; HOLYHEX="micropython/ports/nrf/build-holyiot_...

Thanks; I tried that, but still nothing out of the uart. I also tried changing the target to nrf52840 and nrf52 and using a .hex file for the firmware file, but nothing at all from the uart. This is a device that I successfully flashed about a year ago using openocd, however that will no longer run ...

Hi; I have built the firmware for the NRF52 and also dowloaded the bluetooth stack for the device. Using STLink V2, I have flashed both files: BTFILE="s140_nrf52_6.1.1_softdevice.hex" FWFILE="pca10056-191230-42e45bd.bin" pyOCD flash $BTFILE --target nrf52 [====================] 100% 0009050:INFO:loa...

OK, forget these requests for help, I have solved the problem by using select.poll() on the socket.readline()

This is an attempt at readline using a byte array: a = bytearray(b'0123\r\n45678\r\n9\r\n\r\n') def readline(): global a data=a old=None for i in range(len(a)): new = a[i] if old == 13 and new == 10: data = a[:i-1] a=a[i+1:] return data old = new a = bytearray() return data >>> readline() bytearray(...

I need to read from the socket and cannot use readline() as it is possible that the data does not contain line endings, in which case it will wait forever. So I am reading into a byte string as per the code below, however I realise that using a byte string may not be as efficient as reading into a b...

Hi; This has been discussed before, unless something has changed recently, you have to scan for all devices, and then iterate through them to match your connected SSID and then read the RSSI value from that scan result. I get the rssi (dbm) from my info() function and also calculate a sig strength %...

Look at for example how the tinypico manifest (esp32/boards/TINYPICO/manifest.py) inherits from the base one.

@jimmo Thanks, I just added that to the Build Secrets Post

How can I add a new path to the build so that I can also use it in related files line PORT_DIR
How can I add a new path i.e MY_DIR

If you have a custom manifest file, In order to include the files in the port/modules folder (which are the default frozen files) you need to include the modules folder in your manifest file: freeze('$(PORT_DIR)/modules') OR include('$(PORT_DIR)/boards/manifest.py') freeze("modules") If you don't th...
