Hi

Error 133 (0x85) is a very generic error that could be caused by just about anything. Can you provide some information on what you do exactly? Are you using an nRF52 DK or a custom board of your own? Can you try deleting bonding information in the nRF Connect app as well, and do an nrfjprog --eraseall with the nRF Command Line Tools on your nRF52 device.

Best regards,
Simon

now this work fine but i get another error with my custom project i try to use display everything fine but i get error undefined reference to `nrfx_spi_xfer' but i already drfined

[Simonr]

Hi

Have you enabled the NRFX_SPI_ENABLED as well as the instance you'd like to use in your sdk_config.h file? This is also necessary for the nrfx_spi_xfer file to work properly.

Best regards,

ALL WORK GREAT NOW SPI_RID(DisplayID); now in debug this line is going to unknown function [ UNKNOWN FUNCTION AT 0x000008C8] but i already defined this 

//
// Read the COG ID
//
uint8_t SPI_RID(uint8_t DisplayID) {
tbuf[0] = 0x71;
tbuf[1] = 0;
cs_low(DisplayID);
nrf_drv_spi_transfer(&m_spi_master_0, tbuf, 2, rbuf, 2);
cs_high(DisplayID);
return rbuf[1];
}

Hi

0x8C8 means that the SoftDevice has asserted. This could point to you trying to initialize a peripheral that is already in use for example. What changes have you made to the example project you're working on?

Best regards,

Simon
