Hello,

can you tell me, which specific pins of the WL1835 have to be connected to the 1V8 TTL Interface.

And which pins do I need to 'hijack' in addition. (Enable Wifi high and IRQ for example)

I am trying since 4 days to get the RTTT running but it simply doesn´t seem to work.

Best regards and Thank you,

Samuel

Hi,

Please consult : https://www.ti.com/lit/ug/swru437b/swru437b.pdf

section 9.4 has details on 'sense on reset' pins state for debug mode

section 9.8 has details on WLAN/BT RS232 pins

Hi,

I connected pins 26 (Tx) and 27 (Rx).

Futhermore I set WL_en, UART_DBG_BT and IRQ as high.

But I do not seem to get a connection with the RTTT.

Power is of course also supplied.

What am I missing?

Thank you, best regards,

Samuel

Ensure WLAN_EN and BT_EN are low

Ensure sense on reset pins are set as below

IRQ_WL = 1, UART_DBG_BT = 1, AUD_OUT_BT = 0

Set WLAN_EN to high

Now check RTTT connection.

Hello Mastermind,

this has resolved my issue, I finally manage to connect and download with the RTTT.

What I cannot do for now is, manipulating the Bluetooth modes (BLE & Bluetooth Classic/ and for example hopping mode).

Is there another tool for this or does it work over the RTTT as well?

Do I need to connect to the other Uart Port? (pins 50 - 53)

If so, how do I need to configure it?

Best regards, and thank you,

Samuel

Hi Samuel,

Bluetooth testing can be achieved with the HCI tester tool. Please see more information in the attached guide here:

www.ti.com/lit/swru136

This is handled with communicating to the dedicated UART interface for the BT.

Best Regards,
