I have new device energy power meter with 2 BL0942 chips - one over UART 1 and the other over UART 2.
There is no Tuya Chip.
BL0942 on UART1 working good.
But, I only get zeros on the second uart {with flag 26 set to 1}
Has anyone working BL0942 on UART2 ?
The module is a CBU (BKT7231N)
LED on P9
Button on P24
Flashing is done without desoldering (GND, 3V3, RX1, TX1), no need for CEN, just simple turning on the device for flashing routine.
I found another user with a similar device: https://www.elektroda.com/rtvforum/topic3946128-90.html#21050660.
