• Make sure you are using vsys correctly and check if you should use ADC-ref ref and ref
• add a voltage meter ref
• Add Prometheus metric for voltage

Currently it takes ~2 second for the mbx door open event to reset but if the mail person sits there with the door open for more that 2 second I will get multiple events. I could probably set this to something like 30 seconds or a minutes

I am working with Lora sx127x on a Pico, when I upgraded to v0.28.0 things started to work. But today after I upgraded to v0.28.1 I am no longer able to Tx or Rx. It will find the radio but as soon as I start to Tx or Rx it prints p and locks up (i assume it is printing panic but does not get that far. The 10 second Rx loop work as long as it does not receive any data, but as soon as I send data with another device it locks up.

So I tested my SX1278 and found d01d859 did indeed introduce the breaking change. 😔

$ git bisect good
d01d85930d19a73010853b7ba8648d8811891bee is the first bad commit

    rp2040: add spi busy waits on read and read/write transactions

 src/machine/machine_rp2040_spi.go | 7 ++++++-
 1 file changed, 6 insertions(+), 1 deletion(-)

Code

The addition of this code seems to cause the issue:
Source file /Users/tgilkerson/github/tinygo-org/tinygo/src/machine/machine_rp2040_spi.go

	for spi.isBusy() {
		gosched()
	}

Solution

See if you can run TinyGo from the dev branch and remove this lines until the upstream is fix

To run from dev I think I would do something like this:

• Uninstall the TinyGo extention
• Uninstall TinyGo with brew
• Make change on the dev branch and do go install
• Might have to crate a ln -s to have the TinyGo bin show up in the right place but I am not sure

The power boot module has a 'LBO' Low Battery Output pin. Use it to push a low bat signal which the gateway will turn into a low bat metric

LBO - Low Battery Output. By default it is pulled high to BAT but when the charger detects a low voltage (under 3.2V) the pin will drop down to 0V. You can use this to signal when its time to shut down or alert the user that the battery is low. There is also a red LED connected to this pin.
