53L5A1 SimpleRanging example code timeout error

MSong.4 · ‎2022-11-23

I am trying to get the simple ranging example code for the 53L5A1 to work on the WB55RG board but I keep getting a timeout error.

The text output the example code outputs is "L53L5A1_RANGING_SENSOR_Init failed. Check you're using ONLY the center device soldered on the shield, NO satellite shall be connected".

After looking into the exact error I have found out it is caused by the I2C_WaitOnFlagUntilTimeout function in stm32wbxx_hal_i2c.c.

static HAL_StatusTypeDef I2C_WaitOnFlagUntilTimeout(I2C_HandleTypeDef *hi2c, uint32_t Flag, FlagStatus Status,

uint32_t Timeout, uint32_t Tickstart)

{

while (__HAL_I2C_GET_FLAG(hi2c, Flag) == Status)

{

/* Check for the Timeout */

if (Timeout != HAL_MAX_DELAY)

{

if (((HAL_GetTick() - Tickstart) > Timeout) || (Timeout == 0U))

{

hi2c->ErrorCode |= HAL_I2C_ERROR_TIMEOUT;

hi2c->State = HAL_I2C_STATE_READY;

hi2c->Mode = HAL_I2C_MODE_NONE;

/* Process Unlocked */

__HAL_UNLOCK(hi2c);

return HAL_ERROR;

}

return HAL_OK;

}

The timeout variable is 4096 and it errors when the tickstart goes to 4097.

The stack where to error occurs is
