Issue with range extender?

Hi dialog team,

我们将参考手册范围extender. But we are planning to have different schematics having two main changes

1. No pwm circuit
2. P00 instead of P01 for tx en
3. P01 instead of P02 for rx

Attaching the snapshot of schematics.

We seek for the software changes need to be done for this.

Thankx,
Karan shah

Hi Karan shah,

Hi Karan shah,

You should do the following modifications:

/* TXEN = P0_0 */ SetBits16(P00_MODE_REG, PID , 18); SetBits16(P00_MODE_REG, PUPD, 3); /* RXEN = P0_1 */ SetBits16(P01_MODE_REG, PID , 18); SetBits16(P01_MODE_REG, PUPD, 3);

Also, you should change the DIAG1 to DIAG0 and DIAG2 to DIAG1. Please check the Table 5 from the user manual. The DIAG PORT should have the same as the pin number.

Thanks, PM_Dialog

Hi Dialog Team,

Hi Dialog Team,

Thanks for the quick reply. We were able to start the range extender and check the product.

however while in beacon mode , we are getting 17micro ampere current but when connected to mobile device, it consumes 200micro ampere.

Do we have any standard reading of current while in connected state with mobile?

Regards, Karan

Hi karanshah28,

Hi karanshah28,

The power consumption is closely depended on the connection intervals. Which sleep mode are you using? In 1 connection event, you should get average current consumption around at 120uA.

I have just one more question

I have just one more question,

Is there a way that how can we reduce the current while in connected state?

Hi karanshah28,

Hi karanshah28,

You can reduce the connection intervals and then measure the power consumption.

Thanks, PM_Dialog
