RDV4 power up by smartphone USB/OTG (IOT use Walrus) #113

Closed Mera-balou closed 5 years ago

Mera-balou commented 5 years ago

This issue is not directly linked to walrus, but i don't manage to power up my PM3 RDV4 with my phone (in order to use it with walrus app). I've an One Plus 6T smartphone. @netvader suggested here that it depends on the smartphone USB/OTG power.

Regards

Normally, a y-cable usb and external usb battery. One goes to phone, one goes to pm3, one goes to usb-battery.

USB OTG power and extra support may be enabled in a custom kernel.

iceman1001 commented 5 years ago

It seem that some smartphones are able to power the rdv4 direct without the need for usb battery. I don't think we have a list over which.

Mera-balou commented 5 years ago

Surprisingly, it worked with a smaller cable (amazon basic). But with your recommendation, i bought an Y cable to plug a power bank, IOT to increase antenna performance.

Thanx.

PS : final question for my own curiosity, last commit is from september. Any difficulties to maintain the project or you just wait bigger changes to commit?

I have AT&T Galaxy Note 9 that powers my RDV4.0 directly with no y-cable. I use a amazon basics cable. I power the proxmark with my phone with no problem. I use Walrus app and &Prox app with no issues.

I have a Galaxy S8 and am not having any luck getting the Proxmark3 V4 to read cards. If I use a y cable to connect to both the phone and a USB battery will that generate enough power for the antenna to read?

first of all, have you compiled/flashed lastest firmware (RRG repo) for your RDV4?
