Duplex board by VR2YVE & BI7JTA switching to Simplex after Power cycle
Posted: Tue Apr 17, 2018 7:44 am
I've experienced that this board, designed by VR2YVE & BI7JTA is working fine (have two in service for some weeks now), but there's one 'thing' within the Pi-Star configuration:
If I set the modem/radio board to the 'proper' type ( MMDVM_HS-NPi Hat (VR2YVE) for Nano Pi (GPIO) as instructed in the documentation of this board, it will not hold the duplex setting after power cycle.
It will show Duplex marked ON at the Admin page, but if you check the .ini file (Expert Page ==> MMDVMHost Editor) duplex is set to 0 (zero) and the board will not work duplex (DMU connected to Brandmeister). You have to set it to 1, but after power cycle it is set to 0 again...
Solution: For the Duplex RPi Hat from VR2YVE & BI7JTA, use modem setting MMDVM_HS_HAT (DB9MAT, DF2ET & DO2EN) for Pi (GPIO).
