RAK811/LoRa Module I2C problem
I am using the firmware version version 18.104.22.168 of RAK 811.
Address 0 can not be read by I2C.
An error occurs as shown below.
But Address 1 is OK.
I want to have access to address 0. How can I do it?
In "RAK 811 Lora AT Command V1.4.pdf", "<data_addr>: I2C device register address, enter hex format 16bit" is written.
However, when I confirmed the waveform, it was 8bit address.
How do you specify 8-bit access and 16-bit access?
Yes, currently can't access 0 address
My I2C device has a register at address 0. Is there a way to lead?
