BLE MAC Address is the same for all the SMT32MP1 [43:43:A1:12:1F:AC]

FFont.1 · ‎2021-09-20

Hello,

I'm trying to set-up a BLE GATT service and I'm struggling with the fact of the MAC address being the same for all the STM32MP1 devices.

When I run the hcitool dev this is what I get:

root@stm32mp1:~# hcitool dev

Devices:

hci0 43:43:A1:12:1F:AC

Please help

Probably because an allocation costs money.

For test purposes make sure each within your experiment is unique

Thank you for the reply.

However, I'm not understanding your answer. Are you saying that these MP1 processors don't have an allocated BLE MAC address?

I thought this was an issue with the bluez library as referred here: https://www.raspberrypi.org/forums/viewtopic.php?t=191534.

How can I have multiple devices running at the same time with this non-unique MAC address?
