micro:bit became unable to talk to nrf52832 by RADIO

[Takashi]

Dear Nordic Semiconductor support team

Hi, I got your support using micro:bit with nrf52832 by RADIO in the past as follows.

https://devzone.nordicsemi.com/f/nordic-q-a/41770/how-can-i-make-nrf52832-talk-to-microbit-by-radio-gazell

It did work, but recently, the following makecode editor was updated.

https://makecode.microbit.org/

 

If I built .hex file using this latest makecode editor and download it to micro:bit, nrf52832 Dev Kit cannot receive

any packet, while it works correctly if using the old editor https://makecode.microbit.org/v1

I cannot understand this problem.

I also reported this on Github repository of makecode micro:bit editor. 

https://github.com/microsoft/pxt-microbit/issues/2259

The following is JavaScript code by makecode editor.

(The same between the new editor and the old one.)

radio.setGroup(0)
basic.forever(function () {
    radio.sendNumber(0)
    basic.pause(100)
})

The following is nrf52832 code using RADIO.

Hi, Have you any update? 
I have a similar problem.

 i config ESB right?

uint32_t err_code;
uint8_t base_addr_0[4] = {0x75, 0x62, 0x69, 0x74};
uint8_t addr_prefix[8] = {0x00, 0x01, 0xC3, 0xC4, 0xC5, 0xC6, 0xC7, 0xC8 };

nrf_esb_config_t nrf_esb_config = NRF_ESB_DEFAULT_CONFIG;
nrf_esb_config.protocol = NRF_ESB_PROTOCOL_ESB_DPL;
nrf_esb_config.retransmit_delay = 600;
nrf_esb_config.bitrate = NRF_ESB_BITRATE_1MBPS;
nrf_esb_config.event_handler = nrf_esb_event_handler;
nrf_esb_config.mode = NRF_ESB_MODE_PTX;
nrf_esb_config.selective_auto_ack = false;

err_code = nrf_esb_init(&nrf_esb_config);

err_code = nrf_esb_set_base_address_0(base_addr_0);
VERIFY_SUCCESS(err_code);

But it not work, microbit not recive.

Microbit cfg group 0.

Hi,

You might need to do a bytewise_bitswap() on the base_addr_0, before you set it with nrf_esb_set_base_address_0(). If you have further questions about this, please create a new question.
