I have an Adeunis LoRa pulse counter connected to The Things Network. I can send it downlink frames to change registers in it.
From the documentation: https://www.gowifi.co.nz/specs/PULSE_LoRaWAN_AU915-928_UG_V1.0.0_FR_GB.pdf
Page 72 gives some detail on the registers able to be changed. I have successfully changed register 301 to 5 mins by sending 41 01 00 05 (the extra 00 is because S301 register's size is 2 bytes).
However what would I send to change 321 to Value 1 - this uses Hexadecimal instead of Decimal, and uses bits 0 to 2 for the configuration. Any ideas?
