Good day
My nRF51822 uses the Eddystone example with SDK 12.3.0 in conjunction with S130. When I configure TLM in slot 1, I notice that the temperature is about 6.5 degrees C higher than ambient. Referring to e.g.
I need to subtract 4 times the difference from the die temperature, i.e. 26. However when I subtract 26 in:
D:\Nordic\nRF5_SDK_12.3.0\components\libraries\eddystone\es_tlm.c
it does not make a difference. Even if I subtract 1000, the unadjusted temperature is carried in the TLM frame. My code copied below.
Please assist to point out where I should code this offset?
Thank you
Regards
Jacques
static void update_temp(void)
{
int32_t temp; // variable to hold temp reading
(void)sd_temp_get(&temp); // get new temperature
temp = temp - 26; // ADDED OFFSET HERE
int16_t temp_new = (int16_t) temp; // convert from int32_t to int16_t
m_tlm.temp[0] = (uint8_t)((temp_new >> 2) & 0xFFUL); // Right-shift by two to remove decimal part
m_tlm.temp[1] = (uint8_t)((temp_new << 6) & 0xFFUL); // Left-shift 6 to get fractional part with 0.25 degrees C resolution
}
