Fatal error while adding 2Mbps PHY

[Nabeel Ar]

Board: nRF52810

SoftDevice: s112

SDK version: 17.0.2

I'm trying to enable 2Mbps data rate. So I've added init.config.ble_adv_primary_phy   = BLE_GAP_PHY_2MBPS; in the advertising_init() function. But I'm getting fatal error in advertising_start() function. 

How can I solve this issue and achieve 2 mbps data rate.

Thanks in advance.

Hi.

Could you upload your entire advertising start() function?

Do you have an error code from when it fails?

Hi,

I'm just getting Fatal error msg. 

This is my advertising_start() function.

static void advertising_start(void)
{
    uint32_t err_code = ble_advertising_start(&m_advertising, BLE_ADV_MODE_FAST);
    APP_ERROR_CHECK(err_code);
}

Hi,

Thanks for sharing. But I still can't understand why I'm getting fatal error.

I have few questions.

By enabling 2Mbps PHY, where will the transfer speed increase, In an advertisement or in data transfer?

Is there any example in the SDK with 2Mbps enabled in it?

TIA.

I think you are getting the error because you are trying to advertise on 2mbps.

Maybe you can try to advertise on 1mbps and when the connection is established, you can request a phy update and change to 2mbps for the connection.

Hi

I've changed the code to update PHY after connection establishment and did the same in central too.

Now I'm getting Fatal error after connection. 

How to find which PHY I'm currently using?

Hi. 

Sorry about the delayed response. 

I've been out of office for quite some time. 

Did you resolve your issue, or do you still need assistance on this?
