@misterlisty s = "".join(["%02X" % b[i] for i in range(len(service) - 1,-1,-1)]) resulting in: DEEDAAFB000000000000000000000001 sm = s[:8] + "-" + s[8:12] + "-" + s[12:16]+"-"+ s[16:20] + "-" + s[20:] resulting in: DEEDAAFB-0000-0000-0000-000000000001 Which is however on letter longer than the string above. So check whether in the second group it is really three 0's. Edit: for the second step, you can also write: sm = "-".join([s[:8], s[8:12], s[12:16], s[16:20], s[20:]])

@misterlisty for instance: indexs.group(0) But if you search for a fixed string, you can as well use index, e.g. try: found = response.index("2,1") except: found = -1 it returns either the position of the string or raises an error.

@misterlisty Not sure of the context exactly, but I am thinking you want to extract the "2,1" from the data returned from the CREG+ AT command? I came up with this to extract the RSSI from the LTE connection and use it in a text string for example.. # Get the current LTE signal quality squallteM = lteM.send_at_cmd('AT+CSQ').strip().split() rquallteM = int(squallteM[1].split(',')[0]) # Evaluate the returned signal quality Data rssilteM = 113 - ((rquallteM) * 2) ltesqual = ("LTE RSSI: -{} dbM".format(rssilteM)) The .strip() and .split() operators should do what you want.. Hope it helps.

@misterlisty do you mean upgraded version of your code or of the firmware? And how are you performing the update in the first place anyway?

@misterlisty The second error is from another call somewhere inside your function (line 852 of main.py).

@misterlisty Have a look at the Python methods for string formatting, either the % operator for strings or str.format().

@robert-hh said in Wipy 2.0 and save data on my pc, not in flash memory: Which BN055 module I was asking about the vendor and make of the BNO055 board.

Hi @stefan85e, You can find our example project for the Pysense on GitHub here. It has the main.py with the code and the libraries.

@han I think you're mixing up several different topics: monitoring that LED (or rather the signal that drives that LED, I suppose?) sleep issues LoRa For the monitoring part, it depends on the lengths you are considering. You could probably simply use interrupts to detect when the signal goes up or low, and compute the time difference to find the length of the pulse. What kind of battery are you using? An active LoPy draws about 50 mA even when doing nothing, so even a 5000 mAh battery would only last 4 days without deep sleep. Light sleep would help you save a bit, but you would still be talking about days or weeks, not months, unless you really have a very large battery, or have an external power supply. If you don't use deep sleep you don't need to nvram_save/restore. If you do go to deep sleep, you'll need to wake on pin to wake up when the LED lights up, but you may have issues measuring the first pulse, so I hope it is repeated...

Thank you @robert-hh and @jmarcelino! I will give it a go and report back. :-)

@stefan85e Pycom offers the Pymakr plugin for VS Code or Atom which offers the best integration available. Of course you can also use any IDE and script it using something like https://github.com/dhylands/rshell

@stefan85e MicroPython - as used on the Pycom boards - would count as a different implementation from CPython

@meven What you advised: "python -m pip install pycom" is working for me also, thank you However next, I got this error: "[pylint] E1101:Module 'pycom' has no 'heartbeat' member" but I could ignore it by: # pylint: disable=maybe-no-member pycom.heartbeat(False) pycom.rgbled(0xffff00)
