Having trouble with bluetooth dropping out. Some locos are ok, some are more sensitive, especially at low speed. All my locos are new as I have just returned to the hobby. I am waiting for a power bank to arrive which I will fit to a Dapol class 22, to see if that improves the problem on that one. I also have a number of locos that the HM7000 decoders will not fit into, so I am also considering that a DCC controller will increase the range of decoders I can use. Also, I have an Accurascale Manor (bluetooth offender) which has a pre-installed stay alive. It is not recommended to use a HM7000 decoder with non HM7000 stay alive. So, a few issues which have me wondering about adopting DCC control.
