## Wireshark
|
|
* filter for finding these adverts by mac is `btle.advertising_address == xx:xx:xx:xx:xx || btle.scanning_address == xx:xx:xx:xx:xx`
|
|
* filter for narrowing to without mac is `(btcommon.eir_ad.entry.type == 0x01) && (btle.advertising_header == 0x2506)`

1. 2x 200k resistor
|
|
1. bat\+ -> adc0
|
|
2. bat\- -> adc0
|

2. [adc oneshot read esp-idf](https://github.com/espressif/esp-idf/tree/v5.5.1/examples/peripherals/adc/oneshot_read)

* max usable interval 4000ms seems like
|
|
* 2000ms seems moar stable? idk
