Hello. I am changing the firmware developed using 52832 to use for 52833.
The initial change has been completed, and most operations operate normally.
However, a problem occurs when transmitting data using the nus service. In the existing 52832 firmware, more than 20 bytes were transmitted, but in the changed 52833 firmware, only up to 20 bytes of data are transmitted.
When receiving using the nrf toolbox's uart app, it is received normally, but in the test app, which previously received more than 20 bytes, only 20 bytes are received. Also, only 20 bytes are received from the central device.
The previously developed 52832 firmware used s132 and sdk15.3, and the newly changed 52833 firmware used s140 and sdk17.1.
The following is part of sdk_config.
#ifndef NRF_SDH_BLE_GAP_DATA_LENGTH
#define NRF_SDH_BLE_GAP_DATA_LENGTH 251
#endif
// <o> NRF_SDH_BLE_PERIPHERAL_LINK_COUNT - Maximum number of peripheral links.
#ifndef NRF_SDH_BLE_PERIPHERAL_LINK_COUNT
#define NRF_SDH_BLE_PERIPHERAL_LINK_COUNT 1
#endif
// <o> NRF_SDH_BLE_CENTRAL_LINK_COUNT - Maximum number of central links.
#ifndef NRF_SDH_BLE_CENTRAL_LINK_COUNT
#define NRF_SDH_BLE_CENTRAL_LINK_COUNT 5
#endif
// <o> NRF_SDH_BLE_TOTAL_LINK_COUNT - Total link count.
// <i> Maximum number of total concurrent connections using the default configuration.
#ifndef NRF_SDH_BLE_TOTAL_LINK_COUNT
#define NRF_SDH_BLE_TOTAL_LINK_COUNT 6
#endif
// <o> NRF_SDH_BLE_GAP_EVENT_LENGTH - GAP event length.
// <i> The time set aside for this connection on every connection interval in 1.25 ms units.
#ifndef NRF_SDH_BLE_GAP_EVENT_LENGTH
#define NRF_SDH_BLE_GAP_EVENT_LENGTH 400
#endif
// <o> NRF_SDH_BLE_GATT_MAX_MTU_SIZE - Static maximum MTU size.
#ifndef NRF_SDH_BLE_GATT_MAX_MTU_SIZE
#define NRF_SDH_BLE_GATT_MAX_MTU_SIZE 244
#endif
// <o> NRF_SDH_BLE_GATTS_ATTR_TAB_SIZE - Attribute Table size in bytes. The size must be a multiple of 4.
#ifndef NRF_SDH_BLE_GATTS_ATTR_TAB_SIZE
#define NRF_SDH_BLE_GATTS_ATTR_TAB_SIZE 1408
#endif
// <o> NRF_SDH_BLE_VS_UUID_COUNT - The number of vendor-specific UUIDs.
#ifndef NRF_SDH_BLE_VS_UUID_COUNT
#define NRF_SDH_BLE_VS_UUID_COUNT 2
#endif
I need some information and advice on what I'm missing.
If anyone knows a solution, please advise.
thanks.
