micropython-tinyrtc-i2c VS micropython-lib

I just recently started messing around with the RP Pico and Pico W and was considering using it for a project that would be running 24/7 and needing a battery backed up RTC to ensure time after a reset/power cycle. However, in trying to get a common tiny RTC (DS1307), I have failed to get it to work with the library I found (I'm using micropython), here link. The RTC appear to be the same as that shown in the github link. Also, interestingly when I run i2c.scan, I get results for both devices (RTC and EEPROM) as follows: i2c devices found: 2 Decimal address: 80 | Hexa address: 0x50 Decimal address: 104 | Hexa address: 0x68

I would strongly recommend you to use a DS1307 micropython library instead of reinventing the wheel by reimplementing the protocol required in the datasheet.

This is the current version of my code (excuse the mess it's become..), adapted from https://github.com/micropython/micropython-lib/blob/7128d423c2e7c0309ac17a1e6ba873b909b24fcc/micropython/bluetooth/aioble/examples/temp_client.py

STM32WB55 running MicroPython sounds like it'd suit. Should be fine for the power budget and aioble gives you one of the best BLE libraries on any platform. Documentation is generally good, though BLE is a little light (with some good examples and an active Discord channel!).

Pico (non-W) doesn't have upip (or mip, as that replaces upip now) or urequests because it doesn't have internet access required by them. In theory, you can download urequests from: https://github.com/micropython/micropython-lib/blob/master/python-ecosys/urequests/urequests.py or build your own MP image with it enabled. I don't know if it'll work as you want it to but it's worth a try.

Using SD-card on ESP8266 was more challenging. upip.install('sdcard') does not work.

But ChatGPT truly helped and suggested I find it in Github.

I don't think there's a mip list command or something like that. So your best bet is to look at the subdirectories in https://github.com/micropython/micropython-lib for a list of installable packages.

Do give it another try if you get a chance; I'd be genuinely interested in hearing about your experience. Be sure to check out the awesome list and micropython-lib if you're looking to fill gaps. There are still many holes but they're rapidly being filled in.
